I used to go to that sort of thing back in the 80’s and 90’s. They are fun - and useless. Utterly so.
And anyone that thinks they make a difference to people over the age of 16 is a fool.
These are a LONG way from the useless “team building” exercises of the ‘80s and ‘90s where you could derail the exercises to a point that you could have fun with them. No fun will be had by the participants. In these sessions, you’d be expected to spend all your time looking for ways to self-flagellate yourself over how you haven’t done enough to diminish your influence on your organization and elevate blacks and LGBTOMGWTFBBQ.
And, the seminar is EXPECTED to make a difference to you, and you will be expected to demonstrate the difference it’s made to your superiors going forward.
In other words, this is no longer a pointless “team building”; it’s a Struggle Session where you attempt to show why you should not be summarily ejected from your position to be replaced by someone more acceptable to the Politburo.
After a couple of frivolous lawsuits that paid out millions of tax payer dollars to fired completely worthless former former coworkers who had gotten every possible advantage for being females or black guys... We had to take these same type of "classes". And as you said it was a complete waste of time and money. It was just a big joke that had zero effect on anyone's attitude.
