So my boss asks me if I'd like to take on a big project for a raise. I expressed interest, but said I would need more info. He then pulls me into a meeting and announces that I'm the lead on it. When I told him afterwards that I thought I would have time to think about it, and asked for more details, I was basically treated as ungrateful and yelled at. “You're getting a raise for this, it's not a big lift, etc.” He still wasn't able to give me more details so I could gauge if I could handle the extra work load, and he was so angry that I ended up crying a bunch and losing sleep.
When my contracting company officially offered me the promotion, I raised concerns about not having details about the project, that it might be too much to handle, and how I was treated by my boss. I was basically told it wasn't really a choice, that my job is to provide the government with a service, and I should say yes now and deal with future issues if they come up. After thinking about all the BS I've dealt with from the company and consistent bullying from my boss – I accepted the promotion and shocked the hell out of them when I quit two weeks later.
