Factory workers at Cascades Corporation (CC), which manufactures motorcycle parts, decided to strike. They demanded a minimum wage of $20 per hour, a $5 raise over their current compensation package. The strike lasted one month. When it was over, the workers demanded retroactive pay for the month of the strike and reinstatement to their jobs. There was no poststrike contract agreement addressing what rights and duties either the workers or CC had. By federal law, what must CC provide the workers?
