Awful CEO, 'positivity' above all else, sales-oriented targets even for non-sales roles, salary low for the role type, deliberately unachievable targets, laughable bonus structure, staff scared of speaking out in case they're labelled 'negative' or 'cynical'. I could list about twenty more.
Be careful when reading reviews. Those 'higher up' will say that staff views are listened to, that bullying isn't tolerated and that you'll never be penalised for raising a concern. It's possible that they actually believe this - because concerns never make it past first tier management. People raise concerns with their managers, but rather than listening and passing this on, they're dismissed with 'Don't be cynical', 'Don't be negative' or something similar. Bear in mind that 'positivity' is built into most people's objectives, so when the manager who is in charge of their annual review starts calling them negative for raising a valid concern, people will back down.
