We have a new ETL. I love her to death. Shes a great woman and couldn't be any nicer. However, things don't click with her AT ALL. I was working freight out in an aisle and I had a walkie. As she was walking by, the LOD made a call to another TM on the walkie. She stops, looks and me and says "This walkie doesn't work at all, I don't hear anyone". Me being a good guy, I decided I would switch with her. She was an ETL and I could take a couple of seconds to walk to clerical and swap walkies for one that works. We traded and she carried on. I looked at her walkie and she was on channel two. I know some people forget they to change channels back, but I have to be honest. This wasn't the first time it happened.
