This is a petition to enforce an order of the National Labor Relations Board. The *112Board found that respondent, Rockaway News Supply Co., Inc., had violated Sections 8(a) (1) and (3), 29 U.S.C.A. § 158 (a) (¡1, 3) of the National Labor Relations Act by discharging an employee because of his refusal to cross a picket line at a plant which his duties required him to enter. The undisputed facts upon which this finding is based may be summarized as follows :
'Charles Waugh, the employee whose discharge on March 7, 1950, gives rise to this proceeding, had been employed by respondent as a chauffeur and routeman for about seven years. He was a member of the Newspaper and Mail Deliverers’ Union of New York and Vicinity, which had for some years been contractually recognized by respondent as the exclusive bargaining representative of its employees. Working five days a week (Tuesdays through Saturdays), from 9:45 a. m. to 6:30 p. m., Waugh’s duties consisted of driving a truck along a regularly assigned route and picking up and delivering various newspapers and other publications. Among his scheduled stops was one at the plant of The Daily Review Corporation, Rockville Center, Long Island, New York, publisher of the Nassau Daily Review Star. Before 10:30 a. m. on each working day, except Saturday, Waugh was required to pick up a supply of Review Stars for delivery at subsequent points on his route. This operation consumed about 10 or 15 minutes of each day.
On the morning of Thursday, March 2, 1950, before beginning work, Waugh learned that the Nassau County Typographical Union had placed pickets before the premises of The Daily Review Corporation. He then went to his foreman and told him that he, as a union man, would not cross that union picket line and thereby become a “scab” or a strikebreaker. The foreman suggested that he should not take that attitude, it might mean his job. But Waugh reiterated his position and suggested that copies of the Review Star be brought out to him in some way which would not entail his crossing the picket lines.
Respondent arranged to have its consignment of Review Stars brought on that day to its plant at Valley Stream, from which point Waugh took them and proceeded on his route as usual. Again on the next day, Friday, March 3, respondent had the papers brought by another of its employees to Waugh outside the picket line. On Tuesday, March 7, however, the next day on which Waugh’s duties included picking up copies of the Review Star, his foreman told him that arrangements like those of the preceding Thursday and Friday would not be made and that respondent expected him to cross the picket line. “Otherwise,” said the foreman, “you are fired; if you refuse, you are fired.” Persisting'in his refusal to cross the picket line, Waugh left respondent’s premises. On the following day, Waugh returned seeking to be rehired but the foreman told him that he couldn’t hire him, he had been fired. On each succeeding day for about three weeks Waugh appeared at the respondent’s plant but was not rehired.
On April 7, 1950 Waugh filed a charge and on November 8, 1950 the General Counsel of the Board issued a complaint against the respondent. After a hearing before a trial examiner and an intermediate report by him the Board filed its decision holding that Waugh had a right, guaranteed by Section 7 of the Act, 29 U.S.C.A. § 157, to refuse to cross the picket line and'that accordingly his discharge was in violation of Sections 8(a) (1) and (3) of the Act. Accordingly the Board entered an order which required respondent to cease and desist from (1) interfering with, restraining, or coercing its employees in the exercise of their right to assist the Typographical Union, or any. other labor organization, and their right to engage in, or refrain from, other concerted activities and (2) discouraging .activity on behalf of and membership in the Typographical Union, or any other labor organization, by discriminating in regard to the hire or tenure of its employees. Affirmatively, the order required respondent to reinstate Waugh with back pay, to make available to the Board necessary records bearing on Waugh’s right to reinstatement and back pay, and to post appropriate notices. 95 N.L.R.B.
It will thus be seen that this case squarely presents the question whether it is an unfair labor practice for an employer. *113to discharge an employee who refuses to obey the employer’s orders to perform that part of his regular daily duties which involve his ¡crossing the picket line of another union than his own at another plant than that of his employer. In considering this question we accept the contention of the Board that the refusal of an employee to cross a picket line of another union than his own at another plant than that of his employer is an exercise of “the right to * * •* assist labor organizations * * * and to engage in other concerted activities for the purpose of * * * mutual aid or protection,” which is expressly guaranteed by Section 7 of the Act. Such refusal to cross a picket line is habitual with union workers as this court has recently pointed out,1 2it is frequently of assistance to the labor organization whose picket line is, respected, and it is in a broad but very real sense directed to mutual aid or protection.* But accepting the proposition that the refusal of an employee to cross a picket line is a right guaranteed by Section 7 of the Act does not answer the question which this case poses. For, as the Supreme Court pointed out in Republic Aviation Corp. v. National Labor Relations Board, 1945, 324 U.S. 793, 798, 65 S.Ct. 982, 985, 89 L.Ed. 1372:
“Like so many others, these rights are not unlimited in the sense that they can be exercised without regard to any duty which the existence of rights in others may place upon employer or employee.”
It was in recognition of this limitation upon the rights guaranteed by Section 7 that the Board itself in its decision in Peyton Packing Company, Inc., 1943, 49 N.L.R.B. 828, 843, said:
“The Act, of course, does not prevent an employer from making and enforcing reasonable rules covering the conduct of employees on company time. Working time is for work. It is therefore within the province of an employ- • er to promulgate and enforce a rule prohibiting union solicitation during working hours. Such a rule must be presumed to be valid in the absence of evidence that it was adopted for a discriminatory purpose.”
It is true that in the Peyton Packing Company case the Board found that the union solicitation for which the employees were discharged, although occurring on the company’s premises, had taken place on the employee’s time before or after work or during luncheon or rest periods and not during their working time. It accordingly held their discharges to be in violation of Section 8(1) of the Act. The distinction which the Board has thus made between an employee’s activities on his own time, even though on his employer’s premises, and his activities during his actual working time is a sound and reasonable one and has been upheld by the courts.3
In the cases to which we have referred the distinction between union activities by an employee during working time in violation of the employer’s rules and such activities on the employee’s own time was applied to the soliciting of union memberships in the plant. The right to assist a union of which one is not a member by refusing to cross its picket line is certainly of no higher dignity or importance to the individual than the right to ask his fellow workers in his own plant to join with him in the union of which he is a member in concerted activities which will directly protect or aid in promoting their common interests. We think that the former is subject to the same limitations as the latter. In other words an employee is of ¡course free to exercise his right to refuse to cross a picket line when he is on his own time and his discharge for so doing would doubtless be a violation of Section 8(a) (1). But he is not free to exercise the right during his working time in violation of his employer’s working rules by refusing to per*114form that part of his regular duties which requires him to cross the picket line:4 To hold otherwise would be to permit an employee unilaterally to dictate the terms of his employment which it is well settled he may not do.5
The Board in its decision in this case stated:
“Although Waugh’s refusal to cross the picket line was a protected activity, the Respondent, as a normal incident of its right to maintain its operations, could have required Waugh to elect whether to perform all his duties or, as a striker, to vacate his job and make way for his replacement by the Respondent.”
It will be noted that the Board here concedes that the Respondent could have required Waugh to cross the picket line or “vacate his job.” But by vacating his job the Board seems to mean going out ■ on strike rather than resigning. We cannot follow the Board’s reasoning. For Waugh had no grievance against the respondent nor any economic demands against it which a strike on his part might have enforced. On the contrary, if he had gone on strike it could only have been to assist the striking members of the Typographical Union at the Daily Review Corporation plant by seeking to force his employer not to deal with that corporation. If Waugh’s union had supported him in such a strike it would have been a secondary strike and as such would have been an unfair labor pactice on the part of the union, under Section 8(b) (4) 6 of the Act as amended by the Taft-Hartley Act.
It is true, as the Board points out, that by virtue of the proviso to Section 8(b)(4) Waugh’s individual refusal to cross the picket line cannot be regarded as a violation of the Act or as convicting his union of an unfair labor practice. But the fact remains that the strike which the Board suggests the respondent could, and we gather *115it thinks should, have compelled Waugh to undertake would have been an unlawful one if he had gotten any support in it from his own union. And the fact that Waugh’s act in refusing to perform that part of his duties which involved crossing the picket line was not a violation of the National Labor Relations Act does not make it any the less a violation of his obligation to his employer to perform the duties of his employment or any the less a proper basis for his discharge for failure to do so.
We think that the Board is wholly unrealistic in the distinction which it seeks to make between the discharge of Waugh for refusing to carry his newspapers across the picket line, which it stamps as unlawful, and the suggested replacement of him as a striker after he had been compelled to vacate his job for refusing to do so, which it thinks would have been perfectly all right. For once Waugh had gone out on his one-man strike against the respondent his place could unquestionably have been filled and his name could then have been dropped from the respondent’s payroll under settled principles of law applicable to the replacement of strikers engaged in a strike not involving unfair labor practices.7 Moreover it is inconceivable that Waugh could have won his strike in view of the fact, already adverted to, that any assistance to him by any union would under Section 8(b) (4) have been an unfair labor practice which it would have been the duty of the Board to prevent.
We need only add that we have assumed in reaching our conclusion in this case that Waugh’s refusal to cross the Typographical Union’s picket line was intended by him to aid that labor organization. On the evidence in this case that fact is very doubtful, however. For the evidence indicating that Waugh’s only concern appeared to be with his own standing as a union man. He stated that he did not want to become known as a “scab” or strike breaker by crossing a picket line. He had no intention to aid the picketing union by refusing to handle the newspapers which were being produce4 in the picketed plant. On the contrary it is undisputed that he readily handled and distributed these newspapers on the two days when they were brought to him across the picket line by a fellow employee who apparently did not have the same compunctions.
We conclude that the respondent was not guilty of an unfair labor practice in discharging Waugh; We are supported in this conclusion by the decision of the Court of Appeals for the Seventh Circuit in National Labor Relations Board v. Illinois Bell Tel. Co., 1951, 189 F.2d 124, certiorari denied 342 U.S. 885, 72 S.Ct. 173, in which that court reached the same result upon substantially similar facts. Since Waugh’s discharge was the sole basis for the Board’s conclusions and order it follows that the order must be denied enforcement and set aside.
The petition of the National Labor Relations Board for the enforcement of its order will be denied and the order will be set aside.

. We do not have here a ease in which the order to cross the picket line was a discriminatory order enforced against a union employee in order to prejudice him by reason of his union membership. Such a situation would, of course, involve other considerations.
