The aforementioned colleague support is required to get you through working here. The company has high turnover and resignation of entire departments isn't unheard of.
Goalposts constantly move. You will feel you've misunderstood what was expected of a task because the criteria will change without communication. Employees trying to lead projects are often confused on direction as a result.
Employees receive promotions/additional responsibilities and no pay review.
There is a culture of distrust and suspicion from management to employees.
Rather than focus on overall strategy critical business problems, the CEO micromanages how you plan your work. Employees have a 'task planner' to be filled out a week in advance which is then checked by their manager during team meetings. Every minute of your working week must be accounted for. Each task and estimated duration you plan out is interrogated, and your planner is criticised right down to the format with which you've written it into the document. You are accused of "bloating time" if the CEO thinks tasks should be quicker to complete. Employees are highly-attuned to ensuring their meeting/task duration on their planners matches other colleagues' that they've had meetings with or worked with on mutual tasks to avoid investigation. Managers are told to check planners 3 times a day to review your progress. Employees spend more time worrying about being questioned and covering their backs than working efficiently.
Ironically, the CEO is highly disorganised himself. Your carefully-curated plan is suddenly thrown out of the window for something urgent that he knew was coming up but failed to communicate. If you act on this though, it shows "you don't have enough work to do if you can drop everything". You work long hours for no compensation to get it done due to higher up's lack of planning.
Management are not empowered to approve projects themselves. Everything you do has to be signed off by the CEO. Due to pressure on his time, this is a very slow process which leads to frustration. Often the direction will then be changed as it isn't exactly how the CEO would do it himself and you will be set back to square one.
