No, I am not. Contrary to what TTQ said, employers cannot fire you without cause if you belong to a protected class of employees. They also cannot fire union members without cause, and that almost always requires a long series of documented steps detailing the misbehavior. TTQ stated that the reason they want right-to-work is to be able to discriminate. That's not what it is; it's to prevent unionization and to weaken existing unions.... making it possible to pay lower wages, offer fewer benefits, and also to make it easier to get rid of unwanted employees without all the steps required by most unions.
If you are not a member of a protected class, you can be fired for no reason at all, absent an employment contract. If you are a member, you can still be fired just because they don't want you.... but there may be more documentation required, especially if several members of a particular class are laid off at the same time.
