Yeah mine is not you can be (and are) randomly pinged at any time to go pee in a cup and blow in a tube because they would really really rather that people not be zonked out on the job and make some horrific decision that could impact safety. Sometimes people fail the random tests and get canned but it’s more common for people coming in to test hot and never get started. Good paying jobs but I guess people figure drugs and/or not having to hold back from alcohol on your duty week are better
