Yes, I think every company has different rules and understanding of work policies for its employees. I think that all of them have certain policies, such as calculating overtime and so on.

I have a friend who works in a foreign company, the employees who work are diverse, including Muslims, Catholics, Protestants, Hindus and Buddhists, every time there is a long holiday for them, for example Christmas, Especially for believers who celebrate Christmas, they are given a holiday, as are other loyal employees. This is all for good and fair purposes, of course to keep the company's economy stable.

My understanding is that it is fair, except: when certain holidays arrive and certain employees are not allowed to take holidays and overtime is also not counted, that is indeed unfair, but if the holiday arrangements are appropriate for the company's employees, I think it is fair and where employees who work overtime can add economic value to their income.
