Casual Leave:annual Leave What Is The Difference Please

Dear all,

One funny law has just recently been made in my office to the effect that, all  your casual leave will be deducted from your annual leave, now the impression i have gathered about the casual leave issue is that the Nigerian Labour Law states that you are entitled  to five days of casual leave exclusive of your leave in a year.

Does anyone out there  have an idea of what the law states on what  the general standard should be about issues like this, as i would  really like to take this up with the  overzealous hr in my office always trying to impresss the whiteys with so called "innovation"
