I work the same hours every week, monday to friday, 8 hour shifts, in a manufacturing plant in Ontario. Yesterday at the end of the shift, the management notified the employees that the following shift was cancelled due to computer problems in the office where the orders are processed. There was 16 hrs notice given. There is no contracts or agreements signed at this company. Does Ontario labour law not stipulate that 48hrs notice must be given for shift cancellation or 3 hours must be paid? Thanks
