Personally, if some one have family at weekend is most important moment spent with children, wife and your family by taking rest from working, there will definitely be regrets someday for being able to spend time with family instead of having to work until the holidays. Make your decision keep full time working in a week or you must enjoying great moment at holiday with your family or taking rest for your self.
A person must consider one thing that he has to work as long as he lives. That is why he should not work in a way that can cause great harm to his health. If you work on holidays, you can get 2 times or more of the basic salary. And this is why there are some people who cannot control their greed. They give more priority to money than taking care of their health. Every person should give time to his family even after work. When someone can use 1 day of time properly with his family after working continuously, then he remains spontaneous. This time is certainly important for a person, especially for his working life.
