So I'm a carrier for usps and have been thinking about switching to ups for awhile now, and if I had I could already have five years towards making driver...smh. Anyways, when I start as a loader can I transfer and keep my "seniority" to jump over other loaders? Just curious because in tulare county it's like a 10 year wait unless strange things happen while you wait, and I would want to transfer to a larger city with higher turnover.
