I got a warning letter once because I had a missed business stop with six pieces...
The funny thing (at least to me) was that on the day in question, one of the newbie supervisors forgot that a driver had a personal day that day, and said driver's route sat in the building all morning while I hung out in the back thinking I was getting the day off.
As I was walking out of the building, said supervisor called me to say WE HAVE A BIG PROBLEM...I NEED YOU TO DO THIS ROUTE...
I'd never done the route before, so I had a 45 minute late start on a fairly busy business route with a chit-ton of NDA.
I got all the air off, made my way through the route, made all the pickups on time, got all the resi's off, on the blind.
Except for the one business I got to at 19:15 that happened to be in the 8000 section, tucked away in a residential area. Who knew?
DM was adamant that I receive a warning letter for having six missed pieces, even though I was sent to the wolves that day with a steak hanging around my neck and damn near pulled the whole thing off.
All I could think was, "What lesson am I supposed to learn from this warning letter?". There's progressive discipline for you.
When all you have is a hammer...
