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.
that is true, if it is something that can be useful for many people, of course some public jobs must be done, even though going to work on holidays is something important, which must be done by those who need to serve the community and cannot be postponed any longer, unlike going to work on holidays in the private sector, it can be reconsidered.
I have never seen any public job holder do work during holidays here is on my country. Its depend on countries, factories and also depend on service what you are doing actually. However if it is on the production site where making production 24/7 it depends which day they are select as a holidays and also their is no pressure to do it as for sure. Surely we need a holidays to make fresh our mind and give better service and afford to the factory or work place where you are servicing. I will never provide service if i don’t get the holidays or weekend. It will put pressure on my mind. So it is different from me not to work on the holidays or weekend.
