When workers go on strike, some of their benefits shift from being funded by their employer to being funded by their union’s strike fund. Striking GM employees’ health insurance costs have just shifted to being covered by the UAW strike fund, which covers medical and prescription medications. GM workers have been on the picket line for two days now, because talks for a new collective bargaining agreement hit an impasse. However, negotiations between the union and GM resumed this morning.
