Straight salary, which is one of the limitations. Luckily I feel that the amount is roughly in line with what I would expect, but I am aware someone is profiting off the top, and if I work or bill more, nothing changes. Moonlighting is an option though. And some other opportunities.
Is it ideal? Probably not every aspect. Is it a good job in my situation? Absolutely. If I had found a real independent PP job that I felt was fair in my area maybe I would have taken it. I just want to give the perspective that an AMC job is not necessarily the nightmare often portrayed on these forums.
