I was hired as a seasonal cashier early November and my manager could tell at first that I was pretty quiet and shy but she gave me the job anyways because I said I could come out of my shell. Today my manager called me into her office to have a talk about keeping me after seasonal. She told me she talked to my GSTLs and they said I'm still kinda quiet. She also said she talked to most of the seasonal workers to let them know they were being let go but she said she wants to fight for me and wanted to give me a few more shifts to let me prove I can be outgoing. I feel like I have come out of my shell. I'm just kind of a naturally awkward person. One of my GSTLs told me she even put in a good word for me when discussing who they should keep with my manager. I talk to guests and other cashiers (when we're not busy) all the time. I don't understand what I'm doing wrong? My manager told me not to let her down and I really don't want to. I would love to stay because I've gotten so used to working there and it's my first job. How can I just be more outgoing if I've always been pretty quiet and shy?
