The terms and conditions vary by automaker, because each labor contract is different. But GM factory workers who get laid off start out at "sub pay," in which they receive unemployment benefits, and GM pays the difference, up to most of their salary, for 48 weeks.
After that, laid-off employees go into the jobs bank, where they have the option of taking 85 percent of their base pay -- which averages almost $62,000 a year -- plus benefits, without reporting to work. In the meantime, the company tries to find them jobs elsewhere.
Or workers can get 100 percent of their pay by reporting to either the union hall or the plant, where they may be called upon to perform tasks around the factory or sometimes community service work.
But if there isn't anything to do, workers simply stay at the union hall or factory and find ways to pass the time.
