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.
For someone who has achieved work life balance, they might wonder why people work on holidays. They wonder because for them working on weekdays and holidays is a time to relax with family or do their hobbies. But in reality, someone who chooses to work on holidays is usually not because they are greedy, but because by working they can get extra cash for their life. Around me, there are many people who are not paid properly as employees. But they can't blame the company because that is the salary that was offered at the beginning. In my country, finding a job is very, very difficult. There are millions of people who are still unemployed. Therefore, you can't be picky about work. Because if you don't want a low salary, then someone else will take it. That's why for them holidays are an opportunity to get extra cash. Because if given the choice to be someone with a big salary, I think almost 100% of people will choose not to work on holidays.
