I am in the same boat. I worked 14 hours last week over two days. I am on call everyday, call in about 6 AM. They most often tell me to stay near my phone because the air is almost always late into my building and sometimes I have to run it 2 hours out to drivers! Is it okay for them to have me "On-Call"? Or should I be laid off when the schedule says "laid off"?
I can't bump into the building because I don't have seniority (I was hired on last November). I'm collecting unemployment, but its seriously like $150 a week, not really enough to get by on. I'm looking for some other jobs, and have picked up a few... but keeping my fingers crossed that it gets better soon. I'm guessing most drivers will be taking off a lot of time from March-September... so I hope its only a month or less of this.
On top of all this, they are trying to hire two more drivers! We don't have the work for me, and sometimes another 1-2 drivers... let alone two more! Crazy ole UPS.
