Let's think back on our own job searches and auditions.

How many companies did we contact during that time when we were unemployed - either via web application, resume e-/mailed, phone calls and walk-ins. When we were unemployed and hungry, we probably accepted the first offer. But then there were those times when there was an opportunity we REALLY wanted but another company came through with a 𝘵𝘳𝘪𝘢𝘭 offer: Meet the staff and other departments, let's see if it's a good fit, etc. We accepted. That "bird in the hand" and all that even though it wasn't our first choice. The first choice hadn't made it's "choice" yet.

So you're going along with that "trial" offer --"trial" means not set in stone. No contract was signed. Handshake, verbal. But that one you REALLY wanted finally contacted you. What did you do?

Okay. What was "unprofessional" about your decision?

He signed on under the pretense that his character would be a certain way, and after signing, they changed his character. Not sure exactly what that means, but basically the writers changed the very thing he had signed on for. That's like accepting a job offer for a teaching position at a school but they gave you a receptionist job instead. He didn't get what he signed on for, and even though it's unprofessional to break contract, I also think it's unprofessional to pull the rug out from under someone you've already hired. Again, I don't know the exact details of what changes were actually made to his character, but if it meant a difference in pay or a difference in role position (lead VS side), then that could be a deal breaker for sure.
