Dear Khun Franck
I trust from your order with allow our colleagues keep a knife in locker. Please allow me comment with this issue is a risk for the hotel as followings :
1) Knife is a dangerous object, if we allow colleagues keep in private locker when a fighting happen between our colleagues this is a weapon for them.
2) I think with inventory system with equipment for the hotel. We will not know any equipment was lost from working station.
3) If we allow colleagues keep any equipment in the locker. I believe that we will lost many items in the future even Security Guard at Staff Entrance will search everybody before leaving the hotel.
