If you don't go to the hospital and have no medical certificate, call the company to explain the situation, and the company will handle it according to the system. At most, it is a personal leave, and only the salary of the day is deducted.
If you don't say hello to the company, the leaders directly responsible for the company may regard you as absenteeism, but they can only deduct the salary of the day and then reduce the year-end bonus, but they have no right to fine, because the company is not a law enforcement department. To sum up, it is illegal for them to punish you! Is intolerable!
If they have already done so, you can apply for rights protection and sue them. You are sure to win, but the consequence is that you will lose your job. Regardless of whether you lose this job or not, personally, as a man, dignity is more important than life, of course, more important than work, and you should speak for justice. He makes you uncomfortable, and you make him uncomfortable.
