Bad management. The team leader was appointed strictly based on seniority and the friendship she has with the manager and nothing is done about the lack of professionalism and knowledge she displays time and time again. Hardworking, talented employees receive no aknowledgement for their efforts except on their yearly reviews and all the focus is on the negative. "Friendly reminders" are sent to all employees to put them in their place (for them not to be late, be at their stations etc), instead of adressing singular cases. This does nothing except get the good ones even more frustrated. I have witnessed countless displays of passive agression towards employees and nothing to counterbalance it. The annual raises are not merely enough to keep people around as the environment is kept (sometimes it feels on purpose) basically toxic.
