STOP-GO MAN

An individual seen at road works, this man, (or woman) is tasked with the job of controlling the flow of traffic through said works.

Pretty easy, one would think; turn the sign one way to stop traffic - the other to make it go, yes?
No, the bureaucrats have got involved and there's a little more to it. I can just imagine the interview for such an esteemed position.

"Grab this sign, stand up straight and twist it", the interviewer would say. "On one side there's a 'stop', on the other a 'go'. Y'got that?"

"Now, show me".

The applicant twists the pole this way and that, feeling important at such an honour. He has sat in a room previous to the interview listening to some nob waffling on about how essential a position it is he seeks. To achieve the necessary blue/green/pink with black elephants on it, card. This card means he is a fully trained stop-go man, and authorizes him to control traffic at any road works nationally.

I would have thought the prerequisite for such a position was an operating wrist! But no - the health and safety people are involved to ensure the operator doesn't get rsi or something from all that 'twisting'.
Hoho, the average bloke's wrist gets plenty of exercise what with all the self abuse. Haha - probably the strongest part of him!

Not that I would know anything about that!
