Our union steward wore a jacket advertising the local bar.
Yes, we looked like union labor, not professionals.
yes, they do. I was just this Thursday told by a friend that teaches guitar at the school of rock about a related situation. One of his students came into his lesson and when asked “how’s it going?”, he replied; man school sucks. He proceeded to relay that he wore a Budweiser shirt to school, my friend stated it was a very subdued Budweiser shirt to - not obvious at first glance what the advertisement was for.
Long story short, they pulled the kid into the office, restrained him for a few hours while they evaluated him for drug/alcohol use.
That’s what lack of communication and zero tolerance gets you in at least one MN school (I’m pretty sure this was in Minneapolis or a close suburb).
