I got a promotion at work 2 years ago. This promotion is a totally new job and lets me work from home. Company calls me on Friday and says they want me to do my old job again (a real entry level hell job). They offered no compensation, and no end date. Just two days before this request I signed a job description (describing my normal duties) and a performance evaluation (which was good). I asked them for a raise and because the whole company is in union vote, they wouldn't even have the conversation with me. Now they want to change my job right before a union vote. Is there a way for me to say no? Can they fire me for that? I need some advice. They tell me it's temporary, they tell me I can do the additional work from home. I just don't trust them at all. Help? I'm in CA.
