Actually, to talk about the obligation to work on holidays, first of all we have to understand the type of work. There are some public jobs that people have to consider. Since the people will take precedence first there one has to sacrifice one's interests or the employees have to sacrifice their interests, such as defense workers. And if it comes to private jobs then it would not be right to impose the obligation to work on holidays. However, if the employer wants to get the work done then there must be a financial incentive. So that the employees are willing to work on holidays on their own.
