Management will use behavior as a result of poor mental health against you. If you show any sort of mental instability, you should not expect to advance or have the sympathy/understanding of your higher ups. You should actively expect them to use that against you for any advancement opportunities.
Performance communication is inconsistent or nonexistent. Depending on the mood of the on-site manager (of which there is only one...) of any given day, discipline can range from slaps on the wrists to full write ups without communication.
Employees are not treated equally or as humans by higher ups - mistakes one employee makes will be treated differently than if another employee were to make the same mistake, again depending on the mood of the on-site manager or higher ups on the day when they notice the mistake. Expect to be communicated to about these mistakes as subhuman and without empathy. The higher ups do not care about the employees - only about their performance. This was proven several times via several different communique's. As an example, during the Texas freeze in February of 2021, one of the company executives requested that employees sleep in the store overnight without water, heat, or power. While monetary compensation was offered, this behavior is unacceptable pressure by higher ups to maintain the continuity of business rather than the health of their employees.
