Anyone ever worked ups early shift and woke up at 3AM daily. Orientation day soon and want to know what to expect as a person with a stutter. Any advice? Got a orientation day soon and i have a stutter. Since theres really no customer service and you just lift boxes I went ahead and applied because i was rejected by several jobs because of my stutter and its the only one i could get.
