Everything. Sincerity and honesty would be good places to start.
Stop firing your orientationa nd training people. Onboarding is an imporant thing.
Most co-workers are new and are constantly being fired/quitting and being replaced. Sheer turnover keeps team dynamics in flux.
Wide swath of managers would need to be re-trained or replaced. Managment is the sole issue with the negative workplace culture.
So much to list of what's wrong. Corporate culture, lack of teamwork, negativity induced by poor managment, "leadership" team lacking leaders.
I feel undervalued because I have taken on other people's work and my compensation made no change. Would feel better if managment didn't take advanate of employees who try to pitch in and help out with other responsibilites and duties.
