For the most part people like that tend to burn themselves out and eventually get replaced.
Try what I do -- treat everybody evenly and honestly -- respect from you might earned with time - but don't give it out to them without them earning it.
You will not change anyone - but - with time in ( life - not this job ) you should be able to read people a little bit.
"Uh - Oh - hear comes ETL XXXX - I know hes gonna complain about something" --- that's his job --
"Oh - there's TL XXXXXX - she always has a nice thing to say as she asks me to do something" --
"I gotta walk past cashier woman - there's a good chance she will bust my balls about something" ---- Look you already braced yourself --- so anything negative is gonna just roll off your back --
And the biggie - my personal favorite --- "LISTEN TO HOW THEY TALK ABOUT OTHERS" - If your standing with anyone and TL / ETL / STL - whoever - and weather anything is said between the 3 of you or not -- as he / she walks away ---- and they say - "That prick XXXX ????" There's a 99.9 % there talking about you the same way ---
Personally - the people in my store who are at least polite to everyone ---- I bend over backwards for ---- but that's me
You dont have to like everybody in your store --- except your SFT ------
