Our enterprise adopts the single and double rest system, that is, all personnel are divided into two shifts and take turns to have double rest. How to arrange shifts when encountering legal holidays?

The same is true for airports, subways and other enterprises. It's usually the second break, waiting for the second class. If they happen to be on duty on holidays, such as National Day or even Chinese New Year, they can't continue to work. But if they meet holidays, they must calculate overtime pay or double it. My friend worked in the subway company.
