Thirty-five things your employer may not do
Engage in open or undercover surveillance of employees’ union organizing activities or give the impression that the employees are under surveillance (such as sending supervisors to spy on union meetings, watching the union hall, encouraging other employees to engage in surveillance).
Tell employees that the company will fire or punish them if they engage in union activity.
Grant employees wage increases, special concessions or benefits in order to keep the union out.
Bar employee-union representatives from soliciting employees’ memberships on or off the company property during non-working hours.
Ask employees about union matters, meetings, etc. (some employees may, of their own accord, walk up and tell of such matters. It is not an unfair labor practice for supervisors to listen, but to ask questions to obtain additional information is illegal).
Ask employees what they think about the union or a union representative.
Ask employees how they intend to vote.
Threaten employees with reprisal for participating in union activities. For example, threaten to move the plant or close the business, curtail operations or reduce employee benefits.
Promise benefits if they reject the union.
Form a “company union,” dominate or give financial support or other assistance to a union.

Threaten to close, in fact close, or move plant in order to avoid dealing with a union.
