There is another issue with booking
extended overtime...against cutting off.
If you are continually booking overtime on your own duty there is obviously a problem with that duty.
If you continue to book extended overtime on that duty it is unlikely that problem will ever be addressed.
If you go over by 30 minutes it will cost the business 30 minutes.
If you cut off 30 minutes it will usually cost the business around an hour once travelling time has been added.
You can understand why the business would rather you booked extended and why the issue of overrunning deliveries is never properly addressed.
From a members point of view the sensible thing to do is cut off and therefore create more overtime and more earning opportunity for the entire office.
However some offices have highly dubious overtime allocation practices and i can understand the fear that all of the overtime will end up in the same pockets.
