A lot of money is made by service companies and it goes into the pockets of the people at the top. They are used to offering scraps and watching you scramble to get it. Don't shame your self by accepting their scrapes. Ask for 4 times what you were getting before the layoff. They worried about the ageing of their experienced employees and how they could train a younger generation to replace them. That's why they wanted jobs to become a written process anyone could follow driven, they could train anyone to follow the process. The problem is jobs don't fit a process model well, there are too many things that could go wrong and there is nothing like having an experienced crew that has seen it multiple times and knows how to handle it. Your experience is worth lots of money to the service companies, but more to their customers. Think about it, what customer wants to trust their well to a crew of green hats. Plus what experienced field man wants to get hurt on the job because the green hats did something stupid.
Holdout and ley them come crawling, they are just a bunch of snakes anyway.
