Which is not a mandatory subject matter for good-faith bargaining? a. seniority b. insurance c. pension plans d. strike vote e. All of the above are mandatory subject matters.

The correct answer is letter "D": strike vote.

Explanation:

Collective Bargaining is the act by which employees organized in labor unions negotiate with employers (mainly managers) about compensations and work conditions. Wages, working hours, merit pay, and vacation length, are common topics of discussion between the two parties.

A strike is the stop of operations of a company because of unattended labor union request. The decision of going on a strike or not relies merely on the union and the strike vote is subject to that group only.
