It's not how much they were making, it's certain other concessions, like a job pool where you can go and sit in this room for 8 hours a day, playing cards or gameboy or whatever, waiting for a job to come along, and then have the freedom to turn it down and continue to sit there, drawing pay and benefits, because the job wasn't exactly what you wanted.
I heard about this policy from a gentleman on NPR of all places, he had called in to talk about this subject and he related the story about how he had used this service the company offered him and after about 3 weeks a posting came up that this other guy was offered and he didn't take it, it was exactly what he wanted except that he would have to move to Minnesota, which he was apparently unwilling to do. What would you have done?
