If he pays extra for you, what's wrong?

Anula - i would be clear with your boss. If he needs you to work for this time be clear with him that this is not a normal working time for you. If he really needs this from you, to give up your time with family and friends that only comes once every year, then he must tell you what he is prepared to offer you for this extra-ordinary favour you will do for him. If he is unprepared to offer you anything then you are in your right to not offer him anything. But doing it in this way makes it his decision - and not yours:)

If I were you, I would ask my boss:"Can it wait until I go to work after Holiday?" If no, of course I leave my holiday and go to work, but if yes, I'll continue to enjoy by my holiday:)))))))) But in case when I'm abroad of course I will send my boss far (mentally) and go to work after my arrival:)))))))

saalaaam ala ahmeddddddddddddd

In this day and age, especially with the economy, you should work your job, if your boss asks you to. If you have the option to work a holiday or not work a holiday, then that would be a different situation. But, if he needs you to work on a holiday, I would think that it shows that he has confidence in your work. Therefore, you can be thankful. Also, be thankful that you have a job at all.
