Life and Death Careers

I have no idea whether this is a bug or a feature but it's somehow impossible for me to take vacation time when I'm in the Life and Death careers.  The only time it works is if my sims have actually gone to a vacation lot.  It's impossible to just take a day off work.  Does anyone have this same issue?  I'd love to know whether it's just me or it's a known bug.  I play on PC.
