whats a good excuse for having 3 days of work?

Question

with out notice

Answer 1

Nothing. I had 3 days once and I knew that it was time for me to quit that job. So, if you want 3 days and the work week is really 5, then it is time for you to find another job.

Answer 2

If you are asking about 3 day OFF work, my employer offers vacation time each year. We are actually REQUIRED to use 5 consecutive days once each year. No actual reason is required as long as it is scheduled in advance.
