PN,
If it is your own leave pass then bin it, if it is one of your staff's then bin it and if you do not know who it belongs to then bin it.
You will be adding to the collective greater good and doing nice turn for the individual involved. I have attempted to generate leave passes on the system and have failed. Therefore, if my work does not really care where I am, why should I waste my time trying to tell them
ALWAYS assume NEVER check
