A colleague of mine (part-time loader in a hub) left work last night just past the 5hr mark for his shift. On his way out he was approached by the shift coordinator and told that his leaving was in violation of a "direct work order" and would be considered job abandonment. He was instructed to report to the manager before start of shift tonight. This is further complicated by the fact that other employees in his work area, of the same job classification, and with less seniority were relieved for the night before he was given the option to leave. I've been trying to find documentation in the appropriate rider (date of hire 11-09) but have come up with nothing that touches on part-timer overtime or the protocol for sending people home by seniority. I have never had a problem with using either of those 'rights' but would love to find a hard copy for him before he goes in. So I guess the questions are: Can part timers leave at 5 hours? Can supervisors send home people of lesser seniority without first offering the same to more senior employees? Is there any documentation anyone knows of that he could cite during his meeting tonight? I've advised him of the obvious cautions (punch in before the meeting, make sure a steward is present, don't sign anything, etc.) but are there any other words of wisdom he could benefit from? I thank all of you for your time reading this regardless of any help you can offer.
