Many who were working in the heavily unionised 1970s still have the stinking attitudes of back then, they won't do anything that wasn't in their job description and don't care in the slightest about whether their employer makes money or not. Go to work, do as little as possible, go home again.
From that I can only conclude that you aren't old enough to have lived through the 1970s, at least not as an adult, and that you've fallen for the Tory BS about the behaviour of unions especially back then
I did 2 brief stints at Ford truck plant in Langley, 1975. It was a closed shop so joining the Transport and General workers union was mandatory. On leaving the first time the foreman completes a form on which one of the questions is 'would you employ this person again?', I had to sign the form myself so I saw the good reference he gave me.
Second time I worked there I was on the chassis line, my job involved 2 people mounting the cabs on the chassis, which involved lowering the cab from overhead, stopping the line, slowly lower the cab down until the two halves of a hinge interlocked, bang a steel spigot through and pop a clip on. It was only possible on a 20 ft section of the line because of the hoists position.
From memory 44 trucks rolled off the line on each shift, one day only 43 were rolled off. No ones fault, everyone had completed 44 trucks it was simply due to spacing. When the line stopped, the 44th truck was right at the end of the line but had to move another 20 ft before it could roll, if they did that, it would take it past where the cabs are mounted.
The foreman approached me and the other operative and asked if it would be possible for us to mount another cab, he understood we had done our quota but it would be extremely helpful if we could do just one more.
It was 15 or 20 minutes before the end of the shift so we would be stood around doing nothing waiting to clock off, we both said yep, no problem.
Just as we started to lower a cab the shop steward and a number of 'henchmen' appeared and told us we didn't have to do it, we said 'yeah we know but it's no skin off my nose' to which he said 'no, you don't understand, you really don't have to do it'.
At this point one of his henchmen approached me and whispered in my ear what would happen to me if I mounted another cab so I said to the foreman 'sorry mate but you can see what's going on here, I can't help you'.
When I left about a month later I got the form to sign from the foreman and had a little chuckle.
Would you employ this person again? NO
