What would you do? Part-timer signs extra work bid sheet. Extra work is available on another shift due to call ins. Less senior employee is asked to work over to next sort. Senior employee discovers this and files a seniority grievance. Full-time sup, informs hub manager that senior employee was called. Senior employee produces cell phone records that shows no calls received during time frame discussed. Should employee file a grievance due to dishonesty? Will this be handled in-house by management, or will management forget about it? I can understand someone maybe forgetting they called, but to report that they called in a grievance investigation seems mighty dishonest.
