1 is clearly defined. According to Article 3 of the Regulations on Paid Annual Leave for Employees in the State Council, "Employees who have worked for more than 1 year but less than 10 year shall have an annual leave of 5 days; Annual leave 10 days if it is over/kloc-0 years but less than 20 years; For those who have completed 20 years, annual leave 15 days. (National statutory holidays and rest days are not included in the annual leave) ".

Generally, regular units will have it, but it does not rule out that some private enterprises do not follow the rules.

The question you added is not easy to define. According to what you said, it should be the verbal promise of the supervisor, but now he has changed his mind, which is not written in the labor contract. If we really want to pursue it, there is no evidence. I suggest that you can truthfully report the situation to his superiors and strive for the rights you deserve.
