I learned a lot on the job.... not just what pertained to my job, per se, but also how management consistently ignored issues on the floor and how mental illness was on a rise in my department. There is no room at ANY company for playing favorites yet this was done on a daily basis. In addition, the manager I had at the time, once had printed e-mails regarding co-workers laying out on her desk for anyone to be able to see, spoke in a nasty and unfeeling tone on several occasions behind closed doors, etc. She had a gift for making you feel small and unimportant. If that wasn't enough, a couple of people I worked with had mental issues so deep that it manifested into their personalities (one refused to be accountable and honest regarding her own behavior, the other was a manipulator who comfortably was stirring up trouble and lies within the group) causing tension, animosity and a divide within the team. I just wanted honest communication backed by cohesive efforts but that didn't happen especially when everyone did not share the same definition of what it meant to be a team.
Met some really great people.
Poor leadership, lack of accountability, favoritism, cliques, and dealing with a few adults who behaved like children
