professionals being dicks to "the help"

Had to go to the bank today and saw a guy I know who works maintenance there. We're not friends but I've been seeing him at various places for the last 6-7 years. He used to work at a grocery store I go to and is now at the bank. Good dude, real friendly. Anyway he was walking out as I walked in and during a quick conversation he told me that his maintenance group got chastised by the bank's management recently. They clean late at night, and during the process they put a sign up in one of the halls that's titled "Da Responsibilities." Da as in slang for "the." It's a list of all the cleaning priorities (clean x, make sure to do y, remember to turn off z, etc).
Apparently some senior analyst came by late to pick up something, saw the list, and reported it to management for being unprofessional (due to "da" being used instead of the). He said his cleaning crew has never received complaints about the job they do, but management basically told them they're on notice now.

I asked if the sign could be viewed from outside the bank - perhaps management thought a customer using the outside ATM could look inside and see the sign. But he told me it's not even near the front, it's in a hall.
