Not necessarily. If you have a tyrant for a Full Time Supervisor like I do then you need your union no matter if you’re part time or full time. My Full time Sup is a compulsive liar , messes up people’s time and vacations all the time and doesn’t follow seniority or any rules for that matter. Big screamer and yeller. Constantly has problems with both union members and his own management team. And from what I hear he can barely read or write and has to have other management people including part timers under him do his paperwork and computer work for him. So if you work for someone like that they what do you do ? You can be a model employee and still have problems.
