The Board petitions for enforcement of an order issued against the Great Atlantic and Pacific Tea Company for the commission of two unfair labor practices. The first involves a finding by the Board that the Company violated Section 8(a) (3) and (1) of the National Labor Relations Act, 29 U.S.C. § 158(a) (3) and (1), by announcing the award of a new employment benefit when a Board election was pending, and by granting that benefit to all area employees except those in the voting unit. 1 The alleged violation occurred after two elections conducted among the employees constituting the election unit had been set aside by the Board due to Company interference in the form of unilateral pay increases and promises of future pay raises. On April 26, 1967, two weeks after the second election had been set aside and during the pendency of the third election, the Company issued a letter to the employees in the election unit explaining that they would not receive an additional paid holiday being granted to all other area employees due to the pending election. The letter further stated:
* * * the reason for this is because the National Labor Relations Board has said that an employer shall not increase or decrease the benefits its employees are receiving while an election is pending. A's a matter of fact, the reason we are having to go through another election is because of the increase in the wages which was given to many of our Orlando and Winter Park employees before the last election. Therefore, we are unable to include you in this additional holiday.
We are sure that you are just as tired of this union business and rerun of elections as we are, and we regret that we are unable to give you this additional holiday. We are sure that were we to grant this additional holi *298 day to you prior to this election, the union would again file charges as they have in the past that the Company cheated in the election by buying votes.
The union then filed unfair labor practice charges and the third election was postponed pending their resolution.
The unfair labor practice charged here is based primarily on Section 8(a) (3) of the Act which proscribes discrimination in regard to “any term or condition of employment to encourage or discourage membership in any labor organization.” There is little question that the withholding of the vacation benefit from those in the
voting
unit while granting it to other employees constitutes discrimination against those who are distinguishable only by their participation in protected activity and that such discrimination may to some extent discourage membership in. a labor organization by inducing the employees to vote against the union. The Company, recognizing its obligation in such circumstances to demonstrate that it was motivated by “legitimate objectives,” NLRB v. Great Dane Trailers, Inc., 1967,
It is unnecessary to decide whether the justification advanced by the Company would qualify as a “substantial and legitimate business end,” NLRB v. Brown, 1965,
The Board also found that the Company violated Section 8(a) (1) by threatening an employee, William J. Cairns, with discharge for refusing to give information concerning the union
*299
to the Company’s attorney.

' There is no question that the conduct of the Company supervisor constituted an unlawful threat. Although an employer has a legitimate interest in investigating charges against it, Texas Industries, Inc. v. NLRB, 5th Cir. 1964,
Having concluded that substantial evidence on the record as a whole supports the Board’s findings of unfair labor practices, we turn now to the Board’s order. With regard to the threat, Paragraph 2(c) of the order requires the posting of appropriate notices in all eight stores included in the election unit. Although the Company maintains that the posting of a notice in the North Orange store where Cairns worked would be sufficient to remedy the violation, the Board’s order appears suited to effectuate the policy of the Act and should be enforced. With regard to the vacation benefit withheld from the employees in the election unit, Paragraph 2(a) of the order requires the Company to “make the employees whole * * * by granting the benefits that were instituted on April 26, 1966
with interest
* * (Emphasis added). We are unable to ascertain how the Company is to discharge its obligation to grant the vacation benefit with interest. Accordingly, we think enforcement of Paragraph 2(a) of the order should be withheld pending remand to the Board for clarification. When the Board issues a clarifying order as a result of such proceedings, the order shall be made a supplemental part of the pending record for our final action and decree. NLRB v. Acme Air Appliance, Inc., 2d Cir. 1941,
Enforced in part; remanded in part.
Notes
. Compare NLRB v. Exchange Parts Co., 1965,
The legality of the initiation of the new holiday is not in issue here despite some suggestions contained in the Board’s brief that the Company may have granted the benefit in the first place in order to create a disparity between the employees comprising the election unit and other area employees. The sole issue is whether the Company’s action in withholding the benefit from the employees in the election unit is unlawful.
. “When the resulting harm to employee rights is thus comparatively slight, and a substantial and legitimate business end is served, the employers’ conduct is prima facie lawful. Under these circumstances the finding of an unfair labor practice under § 8(a)(3) requires a showing of improper subjective intent.” NLRB v. Brown,
supra,
. Therefore, even if the legal dilemma erected by the Company would in some circumstances render employer conduct prima facie lawful, the evidence of anti-union motive, which “may make unlawful certain employer conduct which would in other circumstances be lawful,” NLRB v. Great Dane Trailers, Inc.,
supra 388
U.S. at 33,
We also do not reach the Board’s alternative contention that the Company’s conduct was “inherently destructive” of important employee rights within the meaning of NLRB v. Great Dane Trailers, Inc.,
supra
and NLRB v. Erie Resistor Corp., 1963,
. The parties stipulated that:
“During the middle of March 1966, Respondent, by its supervisor, Leonard Richardson, told an employee, William J. Oairns, at the North Orange Ave. Orlando store, that Respondent’s attorney, David Bartholf, threatened to have said employee discharged because he failed to cooperate and give informa-, tion to Mr. Bartholf concerning the Union and its activities during an investigation by Mr. Bartholf of charges which had been filed against Respondent.
