Thank you for all your feedback guys. And here is what happened after I posted in the fourm:
After the 1st day of driving,my superviosr asked me to wait for his further notice for next schedule. 3 days later,I texted him to ask for next schedule date,but he did not even reply me.
Yeah,that is! Put you on a class training for a week,put you aside of the wheels for almost two months,and put you back to the wheel,asked you to drive like a pro. And then kicked you out because you were not experienced.
This also happened to a guy in the trailer next to mine. He was put away from the wheels for more than 2 months,and sucked on the 1st day driving,and then no one called him to drive again.
I'm not wasting any more time for this crap. Even a server job makes much more money than it.
And now,whoever asks me about starting the career in ups as a loader,I'll tell him:To spend 2-3 years to get yourself a degree or a license for a decnet job,or to spend 2-4 years(this is what most full-time drivers told me about the time period to promo from part-time driver to full time driver), working until you get all your joints hurt,getting a paycheck for only $150 per week, for a position that no one can guarantee. Make your choice.
