Depends on region.
In east region their last day is the last day in the year the operation is open.
Also depending on region is whether or not their hire date (when they started as driver helper) is the start of their seniority.
I work for UPS, I might also have a job at a local cafe.
I make like $12.00/hr at UPS, so I have a great hourly rate.. I just don't work the hours I need, and I work third shift which kind of blows.
When I finish my third semester at school I can take my airframe and general exams (there are like three exams for each, except for general which I think only as two. They're all over 6 hours long) At that point I can skip the bid list for Utlilities and take the next available position. I'll lose a dollar an hour.
Then I can finish school, and hopefully find an open mechanic's position at another operation or maybe this one. Haven't decided.
I think at that point, I'm just going to start taking classes in whatever the **** pleases me because UPS airlines will pay for whatever, they don't care. Oh, and I get to jumpseat where ever I want for free.
Current top scale for mechanics is $45.00/hr. (at 5th year) This isn't including bonuses for things like having your IA, powered taxi tests, working at night, and all sorts of other odd *** pay perk **** in their contract.
