Take something simple. Something easy to organise, like revision workshops.

Then faff enough to mess it up. Class sizes of fifty plus. With no designated room to deliver it in.

Take away basic resources like a screen or a whiteboard.

Add some vagueness over what the class is actually teaching. Silliness should determine that your key workers need to do all the legwork, and your basic team should stand around under employed. That will ensure that mountain of Key Worker Paperwork in triplicate gets sorted, and quicker, too.

Manglement types should have a health warning. A lapel badge.

"Let me overcomplicate that for you."
