Guess again. When your pension liability and ins. costs get too high, you'll be out of work.
Prepare to be a contractor. In about 5 years, that will be your only option.
Contracting does give people some options though. You can pack up and leave when you feel like it and you are less likely to have to play corporate political games. Need you to come in on the weekend? That will cost extra? Need me you to stay into the night? Well, they pay for that too. No more free overtime.
