hello i am a semi new ups package handler, but i am now in the union after working at ups for over 30 days. my head supervisor told me that i am not in the union, but i know for a fact i am because i have payed my union due for this month. one of my supervisors has called me the last couple of days telling me not to come into work. But my concern is that when i was hired i was told once i was in the union i was guaranteed 3 1/2 hours a night. is he breaking union rules by telling me not to come in and is there anything i can do? if someone can get back to me as soon as possible that would be fantastic.
