Working Holidays

This also has nothing to do with the class but maybe with another one. My cousin is a Junior at Furman and over Thanksgiving Break she had to turn in a paper the day before Thanksgiving. She also received an e-mail back from the professor that Friday. She told me that her professor was Indian and that he didn't celebrate Thanksgiving. Do you think that its fair to have to write and turn in a paper over the holidays just because a particular teacher doesn't celebrate that holiday? Did anyone have a situation like this one?
