With the brutal economy threatening GM, blue collar workers will give up the "jobs bank" that guaranteed 85% of gross pay until another GM job opened up for those laid off.
White collar workers could transfer or take early retirement but didn't have the option of a buyout if they weren't currently eligible for retirement. Some received severance packages.
Under extreme pressure to make concessions, the UAW will make changes that will even out benefits. The 'jobs bank' has been a huge expense to GM.
