McMaster food service workers took to picket lines Friday after rejecting the university’s final offer in contract negotiations. Students and faculty were delayed getting to the campus, as police reported traffic backups as long as 30 cars. The Service Employees International Union, which represents the 170 striking workers, recommended rejecting the final offer because it “would undermine job security, reduce sick pay and vacation entitlements, and erode take-home pay by imposing ‘expensive’ employee benefit contributions,” the Hamilton Spectator reported. The workers serve meals in student residences as well as in university restaurants like Tim Horton’s. McMaster says it will have managers serving students to ensure those with a prepaid meal plan receive the services they have paid for. A return to the bargaining table has yet to be scheduled.
