This is not ment as a sarcastic remark so please don't take this the wrong way but, what would be in the their personel file that an employee shouldn't see?
I never let an employee have the file alone, but they were always free to see what was there. Sure takes the wind out of a lot of gossip and management mistrust.
Can you prohibit an employee from seeig it? I suppose you can its company property. If there is a specific legal restriction I don't know of any that would.
