A lot of PTers either working doubles or driving air plus their PT job work over 8 hours a day or 40 hours a week. Most don't say anything because it would give the Union an excuse to demand another FT job. The job would be bid by seniority and I am guessing it would not be you.
It can't be bid. My day can not be taken away from me from no one for that matter. No one can be stripped. Naturally it would go to anyway I have top seniority. Two other ppl I know have done this but it was 20 years ago and they can not remember why their pay went immediately to the top rate
