RSV sucks. You are the company's beyotch and you'll be on probation, so you can't even tell them to pack sand.
Good to do the research by asking, but now is not the time to be getting a job sitting reserve to fly an ERJ or CRJ. Unless you get into a company with decent work rules (are there any) or into a company where you won't be on reserve very long it is a crappy gig.
Long days, few days off, etc.
