Posties
There will be loads of Posties that strike that sit in their vans at the ends of their rounds instead of going back to the depot to help clear up. Leftover post often ends up being delivered on overtime costing the company money when it could be done by those who finish early.
There will be loads of Posties that strike that don't cross out unmarked stamps. The amount of stamps I have to cross out while out on the round due to whoever sorted my round not doing so, is ridiculous.
Unorganised and unproductive managers
There are managers who know full well Postie rounds are not equal. Whilst one van share struggles and often has to leave parcels behind, another van share is finished early most days.
Managers will be of no help to Posties they send out blind. They will just leave you to work it out yourself. Why every walk does not have a map, where to park, where post boxes are, where obscure properties are, etc - I have no ruddy clue. Result - post gets mis-delivered, postie brings post back or postie stays out longer and claims more money, postie gets irritated and leaves - RM have to pay to train someone else.
All of this could easily be fixed and make a decent difference to RM profits.
