This case is before the court upon Korn Industries’ petition to review and set aside an order of the National Labor Relations Board and the Board’s cross petition to enforce its order. The first question is whether the company refused to bargain in good faith by:
(a) unilaterally instituting, without first bargaining to impasse during ne*119gotiations, a wage system which included a general wage increase and a merit plan rating;
(b) refusing to furnish the union relevant information relating to the wage system, job standards, and performance records of employees;
(c) informing its employees that the presence of the union would not affect wage policies in any way.
The trial examiner found for the company on all issues. The Board disagreed. It concluded that the company violated Section 8(a) (1) and (5) of the Act.1 We hold substantial evidence supports the Board’s finding that the company refused to bargain in good faith by unilaterally instituting a general wage increase and a merit plan. The Board’s findings on the other issues are not supported by substantial evidence.
The second question pertains to the discharge of Charles W. Campbell, an employee, for distributing union literature in the doorway of the plant building. The trial examiner found that the company’s no-distribution rule was a valid fire prevention measure and that Campbell’s discharge was lawful. The Board concluded that the rule was invalid and consequently Campbell’s discharge was an unfair labor practice within the meaning of Section 8(a) (1) and (3) 2 of the Act. We hold the evidence is insufficient to sustain the Board’s decision.
The union, after being certified in 1963, entered into a one year contract that expired in February, 1965. The union then gave notice of its intention to renew and modify the agreement. The company filed a petition for an election which was held June 2, 1965. The employees voted to retain the union as bargaining representative. A bargaining session was scheduled for June 30, 1965.
On June 26, 1965 the company’s attorney informed the union’s representative that the company had prepared some material to comply with Title VII of the Civil Rights Act,3 which was to become effective July 2, 1965. The attorney asked the union’s representative to review the company’s proposal before the June 30 bargaining session. On June 28 the union’s agent received a three page “Explanation of Job Evaluation and Category System” and a thirty-four page document that classified employees by name into nine separate job categories. The company established a minimum and maximum wage scale for each category. Employees with more than eight months’ service were granted a five cents an hour increase. Employees in several other categories received larger increases. The plan also provided for evaluation of em*120ployees for wage increases as stated intervals over approximately the next four years. The plan provided that the company could revise the job classifications from time to time as conditions warranted.
At the June 30 bargaining session both the company and the union submitted proposals for a new contract. The company requested union approval of the wage plan, asserting that it was designed to comply with Title VII of the Civil Rights Act and Section 6(d) of the Fair Labor Standards Act.4 The company said that an investigation by the Wage and Hour Division of the Department of Labor disclosed the company’s failure to comply with Section 6(d).
The company stated that after the plan went into effect bargaining would continue with regard to wages.
The union replied it was willing for the company to make any adjustments required by the Civil Rights and Fair Labor Standard Acts, but denounced the plan as providing a general wage increase coupled with merit increases on a periodic basis over the next four years or more. The union protested that these provisions of the plan should be the subject of bargaining along with other terms of the contract. The union’s request that the plan be made subject to grievance and arbitration procedure was refused by the company.
During the bargaining session, the union referred to previous negotiations when the company granted a general increase of 10 cents an hour on the ground that the minimum wage law required an upward revision of pay scales. At that time the company declined to make any further concessions, and the union believed the company’s action was disadvantageous to the union and its bargaining- position. The union told the company that it did not want to be maneuvered into that kind of a position again. At this point the company attorney said “that union bargaining had never had any influence on wages in the plant and would not have any in the future.”
To counter the criticism that the plan would be disadvantageous, the company stated the union could take credit for the good features of the plan. The union declined to do this. The company announced that it would put the plan in effect on July 2, 1965, which it did.
It is settled law that an employer violates the duty to bargain collectively imposed by § 8(a) (5) of the Act when it institutes changes in subjects of mandatory bargaining under § 8(d) without first consulting a union with which it is carrying on bona fide contract negotiations that have not yet reached an impasse. NLRB v. Katz, 369 U.S. 736, 82 S.Ct. 1107, 8 L.Ed.2d 230 (1962). Substantial evidence supports the Board’s finding that the company alone, without negotiation, consultation, or conference with the union, planned a general wage increase and a system for evaluating employees and awarding additional merit increases over a period of approximately four years. This plan was made known shortly before the bargaining sessions began, and at the first bargaining session the company announced that it would put it into effect within three days with or without the consent of the union. The finding of the Board that the company would not provide information on the criteria for the merit increases emphasizes the lack of consultation. The company’s plea that it had no information to supplement its plan provided a defense to a separate charge of unfair labor practices, but it did not excuse the company’s failure to consult and negotiate with the union.
In NLRB v. Katz, 369 U.S. 736, 745, 82 S.Ct. 1107, n. 12 (1962), the Court observed that an employer did not violate the Act when, after notice and consultation, it “unilaterally” instituted a wage increase identical with the one which the union has rejected as too low, citing NLRB v. Bradley Washfountain Co., Inc., 192 F.2d *121144, 150-152 (7th Cir. 1951), and NLRB v. Landis Tool Co., 193 F.2d 279 (3rd Cir. 1952). However, neither case factually resembles the situation the Board found at Korn, and the principles they express are not controlling.
In Bradley Wash fountain the union had requested 16 cents and pay for holidays. The parties had bargained over this request. The company, after notice to the union, allowed 15 cents and part of the relief prayed as to pay for holidays. In holding that the company did not commit an unfair labor practice, the court pointed out that its action was not unilateral — that, on the other hand, it was compliance with the request of the union to the extent made.
In Landis Tool Co. the company allowed an increase of 7 cents an hour to 15 pattern makers with whose union it was currently bargaining at the same time that the wage increase was allowed to some 900 other employees in the plant. The court emphasized that the plant’s over-all increase was granted the pattern makers in accordance with an understanding reached by the union and the company.
In neither case was the wage increase made without prior consultation and negotiation with the union in bargaining sessions on the issue of wages, and in neither case did the company attempt without consultation and negotiation to institute a merit plan.
Korn’s wage increase was inextricably linked with its merit system for evaluating employees and awarding additional increases over a period of approximately four years. Bargaining does not take place in isolation and a proposal on one point serves as leverage for positions in other areas. Had the union been offered an opportunity to consult and negotiate with the company on the wage increase, it could more adequately have responded with counter proposals on the merit system and other matters. The interdependence of issues in a bargaining situation is recognized in NLRB v. Crompton-Highland Mills, Inc., 337 U.S. 217, 223, 69 S.Ct. 960, 963, 93 L.Ed. 1320 (1949):
“In the instant case, the wish of the employees to be consulted and to bargain collectively as to the terms of any general wage increase is established by the findings and the negotiations. * * * We do not have here a case where the bargaining had come to a complete termination cutting off the outstanding invitation of the certified collective bargaining representative to bargain as to any new issue on such a matter as rates of pay. * * * The opening which a raise in pay makes for the correction of existing inequities among employees and for the possible substitution of shorter hours, vacations or sick leaves, in lieu of some part of the proposed increase in pay, suggests the infinite opportunities for bargaining that are inherent in an announced readiness of an employer to increase generally the pay of its employees. The occasion is so appropriate for collective bargaining that it is difficult to infer an intent to cut off the opportunity for bargaining and yet be consistent with the purposes of the National Labor Relations Act.
“We do not here have a unilateral grant of an increase in pay made by an employer after the same proposal has been made by the employer in the course of collective bargaining but has been left unaccepted or even rejected in those negotiations. Such a grant might well carry no disparagement of the collective bargaining proceedings. Instead of being regarded as a unfair, labor practice, it might be welcomed by the bargaining representative, without prejudice to the rest of the negotiations.”
Crompton-Highland Mills’ increase in pay was more generous than that which it had offered in negotiations. In Korn the increase in pay was in effect more generous, for the company had made no offer, but instead notified the union that it would put its pay increase into effect with or without the union’s agreement. This is the antithesis of consultation.
Korn’s unilaterally imposed merit system standing alone was an unfair *122labor practice. This issue was decided in NLRB v. Katz, 369 U.S. 736, 745, 82 S.Ct. 1107, 1113 (1962), where the court said:
“The respondents’ third unilateral action related to merit increases, which are also a subject of mandatory bargaining. [National] Labor [Relations] Board v. [J. H.] Allison & Co., [6 Cir.,] 165 F.2d 766, [3 A.L.R.2d 990.] The matter of merit increases had been raised at three of the conferences during 1956 but no final understanding had been reached. In January 1957, the company, without notice to the union, granted merit increases to 20 employees out of the approximately 50 in the unit, the increases ranging between $2 and $10. This action too must be viewed as tantamount to an outright refusal to negotiate on that subject, and therefore as a violation of § 8(a) (5), unless the fact that the January raises were in line with the company’s long-standing practice of granting quarterly or semi-annual merit reviews — in effect, were a mere continuation of the status quo — differentiates them from the wage increases and the changes in the sick-leave plan. We do not think it does. Whatever might be the case as to so-called ‘merit raises’ which are in fact simply automatic increases to which the employer has already committed himself, the raises here in question were in no sense automatic, but were informed by a large measure of discretion. There simply is no way in such case for a union to know whether or not there has been a substantial departure from past practice, and therefore the union may properly insist that the company negotiate as to the procedures and criteria for determining such increases.”
Despite the admonition in Katz that the union may properly insist that the company negotiate for the procedure and criteria for determining merit increases, Korn refused to do so, even after it had offered to continue negotiations with the wage plan in effect. On August 13, more than thirty days after the merit system had been placed in effect, the union made a written request for certain items of information relating to the job descriptions and the new wage system. The company attorney stated the request was “silly” because he had already given the union the information. The union representative acknowledged that the company gave him a list of the employees, their hiring dates and their wage rate, but protested the company gave no information or data that was used by the company to put empolyees in certain groups, and nothing about the content of the jobs involved in the groupings. To this the company attorney responded that the union representatives were familiar with the furniture industry and that “ * * * if there is anything you don’t know you can ask the employees.”
At this same bargaining session the union pressed its objection to the merit system because it left the question of wages solely to the discretion of the company for a period of about four years and neither the union nor the employees would have recourse to what the company did in the matter of wages. To this objection the company’s attorney replied, “Oh yes, there is a recourse if an employee doesn’t get a raise, he can ask us and we will tell him why.”
There is substantial evidence for the Board’s finding that Korn’s institution of the wage increase and merit system was in bad faith and in derogation of its duty to bargain. Not only did the company make the change without conferring in good faith with respect to wages and conditions of employment, but it also persisted in its refusal to furnish meaningful information upon which consultation could be based after the system went into effect.
The Board was not required to accept the company’s unsupported contention that its wage plan was necessary to comply with the Civil Rights Act and the Fair Labor Standards Act. An across the board hourly increase and a merit system extending over a four-year period could be considered by the Board as ir*123relevant to the requirements of the laws to which the company referred.
Furthermore, the Board found that seven months after the company unilaterally instituted the wage system the company attorney proposed a revision of still further wage increases in order to comply with the Civil Rights Act. When the union representative asked why it was necessary to make further changes to effect compliance, the company attorney mentioned as one of the reasons, “employees were leaving for better jobs and the company needed to put in another increase to stop people from leaving the factory.” The Board was justified in drawing the inference that the company’s unilateral action on wages was not limited to the requirements of the Civil Rights Act.
The Board found the company also violated the Act by failing to furnish the union relevant information about the new wage system, job standards and performance records of employees.
An employer must provide relevant information to union representatives so that they can bargain effectively. NLRB v. Whitin Machine Works, 217 F.2d 593, 594 (4th Cir. 1954), cert. denied 349 U.S. 905, 75 S.Ct. 583, 99 L.Ed. 1242 (1955). But it cannot be required to furnish information which is not available to it. NLRB v. United Brass Works, Inc., 287 F.2d 689, 697 (4th Cir. 1961). The uncontradicted evi dence shows that the company furnished all the information it had about its new plan. This information was less complete than the Board deemed necessary. The absence of detailed information is consistent with the company’s explanation that the plan was hurriedly made. This might reflect upon the plan, but the paucity of the data does not establish that other information was available. The Board’s finding on this issue is not supported by substantial evidence.
The Board found the statement made by the company attorney that “ * * * union bargaining had never had any influence on wages in that plant and would not have any in the future,” tended to interfere and restrain employees in the exercise of their § 7 rights and thereby violated § 8(a) (l).5 The Board also found the statement evidenced an intention not to bargain in good faith.
The statement was made at a bargaining session during the dispute over merits and reasons for the unilateral wage plan. No doubt the Board was justified in considering the statement as evidence disparaging the company’s claim that its wage plan was a bona fide effort to comply with the Civil Rights Act and Fair Labor Standards Act. The evidence, however, does not sustain the Board’s finding that the statement tended to interfere and restrain employees in the exercise of their § 7 rights.
Under other circumstances the statement might violate the Act.6 But here, within the context of the bargaining session at which the statement was made, it cannot be considered an independent violation. It was simply a part of the argument that centered on the improper wage plan. The division of one violation of the Act into many violations should not be encouraged. Nor should the Board, or courts, inhibit discussion at the bargaining table by imposing a penalty based upon isolated statements made in the heat of argument. Cf. NLRB v. Frontier Homes Corp., 8 Cir., 371 F.2d 974 (1967).
We reject the company’s suggestion that its wage plan did not violate the Act because of the good faith character of its negotiations. The Board can conclude an employer’s unilateral in*124stitution of a wage plan during negotiations violates § 8(a) (5) without finding subjective bad faith at the bargaining table. NLRB v. Katz, 369 U.S. 736, 82 S.Ct. 1107 (1962). Failure of the company’s defense, however, does not rest solely on Katz. Several elements — the lack of substance to the claim that the wage plan was designed to comply with new legislation, the paucity of information concerning it, and the company attorney’s comment on the union’s ineffectiveness — combine with the unilateral institution of the plan to provide substantial evidence for the Board’s decision that the company failed to bargain in good faith.
II
The Board found that the company engaged in unfair labor practices within the meaning of § 8(a) (1) and (3) of the Act by discharging Campbell for violating a rule that prohibited the distribution of literature. The Board held that the enforcement of this rule was in itself an unfair labor practice within the meaning of § 8(a) (1) of the Act.
The rule provides:
“Distribution of literature: Good housekeeping on the premises contributes to safe working conditions and quality work. In order to maintain good housekeeping, the distribution on the premises by anyone of any literature, pamphlets, or handbills will not be permitted except as made by Korn Industries in aid of is operations.”
Campbell violated this rule on four occasions. In the latter part of August, 1965, he was observed distributing union literature in the doorway of the factory to employees entering the factory. The plant superintendent read the rule to him, explained the rule, and verbally warned him not to violate it again. On September 17 and October 13, Campbell violated the rule by distributing literature at the same place. On these occasions he was given written warnings. A notation on the first of these warnings indicated that the business agent of the union had been consulted by the company. The agent had told the company that he would see that it did not happen again. The superintendent told Campbell that if he violated the rule again he would be discharged.
On October 21, Campbell again distributed union literature in the same place, and was discharged.
The doorway where Campbell distributed the literature was a nonworking area of the plant. It opened upon a hallway that led to a machine shop about 12 feet away. The main working area was 30 or 40 feet distant.
A rule prohibiting employees from distributing union literature on their own time, in nonworking areas of the employer’s plant, is presumptively invalid. Lack of an anti-union motive is immaterial. Such a rule only can be upheld on a showing that special circumstances make the rule necessary to maintain production or discipline. Republic Aviation Corp. v. NLRB, 324 U.S. 793, 65 S.Ct. 982, 89 L.Ed. 1372 (1945); NLRB v. Lexington Chair Co., 361 F.2d 283 (4th Cir. 1966); Peyton Packing Co., 49 NLRB 828, 843 (1943). The Board applied this presumption in reaching its decision that the rule was invalid and Campbell’s discharge was unwarranted.
Company officials testified the purpose of the rule was to insure good housekeeping and safety of the plant with respect to fire and other hazards. The rule was made about 1954. Fires had damaged the plant in 1942 and 1952.
Although the rule on its face applied throughout the company’s premises, it was not interpreted by the company or its employees as broadly as it was written. Union members distributed literature in the parking lot area of the company’s premises without interference by the company. Enforcement of the rule was confined to the factory area.
The rule also was subject to another exception which, permitted union litera*125ture. The contract between the union and the company provided in Article 8:
“The company shall erect a bulletin board in the hallway near the time clocks for the exclusive use of the union provided however that all notices so posted will be signed by an officer of either the Local or International union.”
The bulletin board was maintained with the exception of a short time when it was obstructed by a drink machine while a lunch room was remodeled. It was not obstructed at the time Campbell was discharged.
The Board attached no significance to the fact that distribution of union literature was permitted on the company parking lot and that a bulletin board was maintained for the exclusive use of the union. General Counsel took the position that the non-distribution rule is invalid even if there are other available means of communication among the employees or between the employees and the union. He relied upon NLRB v. United Aircraft Corp., 324 F.2d 128 (2d Cir. 1963), cert. denied 376 U.S. 951, 84 S.Ct. 969, 11 L.Ed.2d 971 (1964), which held that the Board need not consider alternative means of communication in applying the presumption óf invalidity. On this question the circuits differ. Contrary conclusions were reached in Republic Aluminum Co. v. NLRB, 374 F.2d 183 (5th Cir. 1967) and NLRB v. Rockwell Mfg. Co., 271 F.2d 109 (3rd Cir. 1959). The issue presented by these cases, however, is not squarely before us for decision. In NLRB v. United Aircraft Corp., 324 F.2d 128 (2d Cir. 1963), cert. denied 376 U.S. 951, 84 S.Ct. 969 (1964), the company rule prohibited distribution of union literature in nonworking areas of the company’s premises. Under these circumstances, the court pointed out, the alternatives were distribution through the mail, newspaper advertisements, television and radio, and on public sidewalks and street corners.
The factual situation before us is different. The company’s position is not dependent upon off-plant distribution as an alternative to in-plant distribution. The uncontradicted evidence discloses that the company allowed in-plant distribution on its parking lot and by means of the union bulletin board which the company maintains near the time clock. The company prohibited distribution of literature only in the factory area.
We believe that the company’s distribution rule and practices, along with the contractual provision allowing a union bulletin board,7 must be viewed together. When all of these elements are considered it is apparent that the company did not flatly prohibit distribution of union literature on its premises. The union offered no evidence that the limitation upon distribution in the factory area was not for purposes of good housekeeping, safety and fire prevention. The evidence demonstrates that special circumstances do exist justifying the company’s regulations. The rule which Campbell violated was valid. Campbell’s discharge was lawful.
We conclude that those portions of the Board’s order which refer to the unilateral change in wages and the refusal to bargain concerning wages should be enforced.8 In all other respects enforcement of the Board’s order is denied.
