That's their own fault then. If you want more money, that's absolutely fine, but they need to know the risks entailed in those mega-deals.

It's like all the rest of us when it comes to contract negotiations. Negotiate, negotiate, negotiate. Don't just look at $/hr. Look at PTO, 401k match, benefits, etc. Put your foot down hard on things you don't want to compromise in. Say, "Ok, I'll take /hr less, but you WILL give me __ weeks PTO minimum and vested immediately."

I'd still feel bad if you took more money in said example but have a pitiful PTO because everyone should have decent PTO. However, at the same time, you have to push for that if it was so important to you. Same boat as I feel with LoL pros who get boned by buy-outs. Got to account for that if you felt it would screw you.
