29 CFR 452.78 – Expenditures by employers
(a) As an additional safeguard, section 401(g) provides that no money of an employer is to be contributed or applied to promote the candidacy of any person in an election subject to the provisions of title IV. This includes indirect as well as direct expenditures. Thus, for example, campaigning by union stewards on company time with the approval of the employer would violate section 401(g) unless it can be shown that they are on legitimate work assignments, and that their campaign activities are only incidental to the performance of their assigned task and do not interfere with its performance. This prohibition against the use of employer money includes any costs incurred by an employer, or anything of value contributed by an employer, in order to support the candidacy of any individual in an election. It would not, however, extend to ordinary business practices which result in conferring a benefit, such as, for example, a discount on the cost of printing campaign literature which is made available on the same terms to other customers.
(b) The prohibition against the use of employer money to support the candidacy of a person in any election subject to the provisions of title IV is not restricted to employers who employ members of the labor organization in which the election is being conducted, or who have any business or contractual relationship with the labor organization.
