Can my supervisor cancel vacation leave requests that have been already approved because of an influenza outbreak and possible pandemic?

Yes. Your supervisor or department head has the authority to cancel any pre-approved vacation leave requests when it is in the best interest of your department or the University, such as in circumstances where there are serious staff shortages as a result of illness. Your vacation leave could also be cancelled if your job is considered "essential" under university policy.

Check with your supervisor to determine if your job is considered essential. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
