Finished half of my annual leave

I have already enjoyed my half of my annual leaves. There is only one week remained for me to escape from my working environment. But never think that I can totally escape from my work, I received a call from my manager to ask me go back to work even though I am on Annual leave now. I understand that there is shortage of power but I think this is not my own problem. I refused her request of course. I really hated the feeling of standby to workduring holiday.
