It didn't catch on
with my friends and I either. I wore shirts and ties all week. When it was time to unwind, it was jeans and a casual shirt.
Plus when I had to, the business sport coat cam off, and I helped with the labor end of things in order to show the younger crews how to finesse the stores so they looked their best. Hard work was never beneath me.
As a manager and supervisor, I never had and us and them attitude. Team effort.
