I am a part-time local sort employee. I audit international packages. I was asked to cover drive for 2 weeks during peak season and forced to work the local sort on the same days. According to my coworkers and the teamsters southern region agreement book (Article 58 Section 3)... I should be compensated at the rate applicable to the highest rated classification for all work performed during that day. This was not the case when I received my paychecks. I was making my regular pay for the local sort and not cover driver pay. I called and spoke with the payroll clerk who said she would speak to the center manager but she was sure it was accurate. She also told me other employees from the preload were cover driving and working their regular jobs as well and did not ask for a payroll correction. Can someone enlighten me on this subject matter? Thanks.
