The National Labor Relations Board seeks enforcement of its order against The Lorben Corporation issued May 11, 1964 and reported at 146 N.L.R.B. No. 174. As the result of our determination of the merits we find it unnecessary to discuss the challenge to the procedure of consolidating the original charge and complaint with the second ones other than to say that the procedure was proper, see Coca-Cola Bottling Co. v. NLRB, 195 F.2d 955, 956 (8 Cir. 1952).
*347The basic facts are simple and undisputed. On April 1, 1963 Local 1922, International Brotherhood of Electrical Workers, AFL-CIO, began organizing respondent’s plant and secured the adherence of four of the 25 or 26 employees. On April 4 the union held a meeting to decide what to do about the discharge of one of the employees believed to have been discharged for union activities. A strike was decided upon and picketing began the next day with placards reading: “Employees of Lorben Electronics Corporation on Strike — Please help us maintain decent working conditions.” About two days later the discharged employee asked respondent’s president whether he wanted to have any discussions with the union’s officials and the president said he did not want to do so. Subsequently, respondent’s president, on advice of counsel, prepared a paper with a question: “Do you wish Local 1922 of the Electrical Workers to represent you ? ” Under this were two columns, “yes” and “no.” The plant superintendent handed the sheet to each employee explaining to each that each was free to sign or not sign. This was done throughout the plant. All of the employees signed in the “no” column. There is no evidence of any employee hostility to the union and the Trial Examiner found an absence of any “other unfair labor practices.” However, the Examiner found that the respondent had violated the Act. While the Examiner mentioned the failure of respondent to advise the employees of the purpose of the interrogation and to assure them that no reprisals would follow, he based his decision primarily on his finding that the respondent had no legitimate purpose for the interrogation. The Board based its decision on the first two reasons and refused to rely on the third. We deny enforcement of the Board’s order.1
Employer interrogation ,of employees as to their desire to be represented by a particular union is not coercive or intimidating on its face. It is extremely difficult to determine how often and under what circumstances threats will be inferred by the employees. The resulting confusion from efforts to set up basic ground rules in this field is carefully explored by Prof. Derek C. Bok, The Regulation of Campaign Tactics in Representation Elections Under the National Labor Relations Act, 78 Harv.L. Rev. 38,106 (1964).
The problem of delineating what is coercion by interrogation has resisted any set rules or specific limitations. The Board’s original determination that interrogation by the employer was unlawful per se, Standard-Coosa-Thatcher Co., 85 N.L.R.B. 1358 (1949), was disapproved by the courts and the Board retreated to the position that interrogation would only be unlawful where it was found to be coercive in the light of all surrounding circumstances. As the Board stated in Blue Flash Express, Inc., 109 N.L.R.B. 591, 594 (1954): “We agree with and adopt the test laid down by the Court of Appeals for the Second Circuit in the Syracuse Color Press case [209 F.2d 596, cert. denied, 347 U.S. 966, 74 S.Ct. 777, 98 L.Ed. 1108 (1954)] which we construe to be that the answer to whether particular interrogation interferes with, restrains, and coerces employees must be found in the record as a whole.” In Bourne v. NLRB, 332 F.2d 47, 48 (2 Cir. 1964), this Circuit reaffirmed this comprehen-
*348sive approach and we attempted to suggest some of the many factors that must be considered anew in each case to determine whether a particular interrogation is coercive:
“(1) The background, i. e. is there a history of employer hostility and discrimination?
“(2) The nature of the information sought, e. g. did the interrogator appear to be seeking information on which to base taking action, against individual employees ?
“(3) The identity of the questioner, i. e. how high was he in the company hierarchy?
“(4) Place and method of interrogation, e. g. was employee called from work to the boss’s office? Was there an atmosphere of ‘unnatural formality’?
“(5) Truthfulness of the reply.”
See also Welch Scientific Co. v. NLRB, 340 F.2d 199 (2 Cir. 1965).
Recently, the Board has withdrawn from this more comprehensive approach and has sought to establish the rule that employér interrogation is coercive in the absence of a showing that (1) there is a valid purpose for obtaining the information; (2) this purpose is communicated to the employees; and (3) the employees are assured that no reprisals will be taken, cf. Johnnie’s Poultry Co., 146 N. L. R..B. No. 98, p. 7 (April 17, 1964); 2 Bok, supra, at 107. In the instant case, the Board applied this rule. It acknowledged that respondent had a valid purpose in conducting the poll, namely, to determine whether the union represented a majority of its employees for the purpose of deciding whether recognition should be extended. Yet the Board found that respondent had committed an unfair labor practice simply because of “the manner in which the poll was conducted, particularly the fact that Respondent did not explain the purpose of the poll to all of the- employees, and did not offer or provide any assurances to the employees that their rights under the Act would not be infringed.”
To enforce the Board's order which rests on this narrow ground alone, would be to depart from the line of decisions of this Circuit cited above, once approved by the Board, and we are not so inclined. While it is true that questioning can very well have a coercive effect where the purpose is not explained and there are no assurances against retaliation, cf. NLRB v. Camco, Inc., 340 F.2d 803 (5 Cir. 1965), we hold that the absence of these two factors, without more and in the face of the undisputed facts in the record of this case, fails to show coercion within the meaning of section 8(a) (1).
The record of this case shows the following. Respondent owned a small plant of some 25 or 26 employees. A strike was called and a picket line had been set up after an employee had been discharged. The discharged employee asked management if it wanted to hold discussions with the union. The poll of employees followed. It was completed within the same day and this was the only poll that was taken. There was no showing of any employer hostility to the union nor any showing of any “other unfair labor *349practices.” 3 This record does not contain substantial evidence sufficient to support the Board’s conclusion that the interrogation was coercive and enforcement must be denied.
. The Board, modifying the Trial Examiner’s order which forbade interrogation concerning union activity “without legitimate purpose and without proper safeguards,” ordered respondent to cease and desist from:
“(a) Interfering with, restraining, or coercing its employees in the exercise of their rights guaranteed by Section 7 of the Act by interrogating them concerning their union activities or sympathies or by polling them in a manner constituting restraint and co'ereion within the meaning of Section 8 (a) (1) of the Act.”
. However, in Johnnie’s Poultry Co. there were findings that the employer had threatened to close the plant, showed evidence of “union animus” and demonstrated an absence of good faith, as well as an unlawful refusal to bargain in violation of section 8(a) (5) of the Act. Similarly in Frank Sullivan & Co., 133 N.L.R.B. 726 (1961), there was a finding that the employer had “indicated an antipathy toward the Union”; and in Orkin Exterminating Co., 136 N.L.R.B. 399 (1962) it was recognized that the questioning occurred “in á context of threats to close the plant if the Union organized it” and after “pressure [had been] put on employees to withdraw their union cards.”
. The Trial Examiner’s report is replete with such statements as “I reach the foregoing conclusion notwithstanding the absence of expression of employer hostility to the Union, or of other unfair labor practices” and “There is no evidence of union animus by the Respondent.”
