Generally speaking, this kind of workplace can communicate directly with human resources regardless of sexual harassment. The human resources department will conduct a series of investigations, and if there is a problem, he will be warned or transferred.
If you have a conflict with your immediate supervisor and are suppressed, you don't want to wait and die. The only choice is to report to the big boss who supports you for help.
Because there is a big difference in rank between the two sides, and the big boss is busy, it is not appropriate to ask him out to talk privately. But to keep it a secret, you can find him after work.
It is best when no one is off work on weekdays, followed by his weekends in the company, and the time before going to work on weekdays is generally no more than 30 minutes. In this matter, it is obvious that the boss is wrong.
As a manager, you can't just care about the interests of the department and ignore the interests of the company; Before training, promotion and punishment of an employee, it should also be approved by the superior and recognized by the human resources department.
The relationship between superiors and subordinates is cooperative, not dependent or subordinate. This boss regards the interests of the department more seriously than the company, and asks his subordinates to be loyal to themselves rather than the company, which has seriously violated the post responsibilities and is obviously incompetent.
If the company is small and there are many things to do, leave, but it is not recommended to send an open letter. Because the next time you join the company, the new company will do one thing: background check. Making things too ugly is not particularly good for you to find a job in the future.
