John, the district manager contacted me in response to the poor display of professionalism and general lack of humanity I witnessed as a described in my last review.
He asked me to brief him on what had happened on Sunday and I explained how is stand-in manager was acting like a two year old and creating a hostile work environment for other employees, and an overall tense and awkward atmosphere for customers. He took my concern seriously and seemed genuinely empathetic. He stated that Einstein's does not tolerate this type of behavior and he's very saddened and disappointed that Cody behaved this way, especially in front of customers. John assured me that he and the general manager would address the issue and also go over possible training flaws to prevent this in the future.
Overall, I'm glad that someone in management is now aware. Hopefully the service, atmosphere, and Cody's ethics will improve and he can learn and grow from this experience instead of regress.
