Voluntary contribution means a contribution given freely, without pressure or coercion. A contribution is not voluntary unless it is made in an amount determined by the contributing employee, except that where an amount for a gift is included in the cost for a luncheon, reception or similar event, an employee who freely chooses to pay a proportionate share of the total cost in order to attend will be deemed to have made a voluntary contribution. Except in the case of contributions for a gift included in the cost of a luncheon, reception or similar event, a statement that an employee may choose to contribute less or not at all shall accompany any recommendation of an amount to be contributed for a gift to an official superior.
