My first job straight out of high school was a dock worker for ups freight in 2008. Got my class A in 2010 and was reclassified to p&d driver and been driving since. Recently we got a new T.M and was told every driver needed to get their tankers endorsement by July 9,2015 or else you could not drive until u get it. My terminal was so short handed at the time I couldn't get the endorsement by the deadline. Me and my T.M agreed I'd go to dmv July 16,2015 to get my endorsement. 45min of me being at dmv T.M calls me to leave dmv right away and head back to work to start driving. I refused to go back until I was done at dmv. I go back when I was done I was sent home. I go in to work next day I'm told I'm discharged for insubordination. Should I get a labor attorney or did I mess up big time?
