Did you know that in NB the following holydays: Boxing Day, Victoria Day and Thanksgiving Day are not paid public holidays?

So if you work in NB for Employer that is not located in NB you will not just get paid but you also have to work on those days.

What is the difference between paid public holidays and the prescribed days of rest?
Paid public holidays are identified in the Employment Standards Act and there are eight in total: New Year's Day, Family Day, Good Friday, Canada Day, New Brunswick Day, Labour Day, Remembrance Day and Christmas Day. These also happen to be "prescribed days of rest".

There are three prescribed days of rest that are not considered "paid public holidays" in the Employment Standards Act are Boxing Day, Victoria Day and Thanksgiving Day.
