I once worked in a factory assembling double glazed patio doors the boss was great, the foreman was a pain in the butt, one of my duty's was to unload the truck delivering the glass sealed units with a forklift. Lift them off the truck, drive through the door and take them to the far end of the factory where they were stored until needed. The problem was on entering the door there were three large heater units that I had to raise 19 sealed units above, but after each heater there was a steel beam, so the load had to be lowered to almost ground level.
Think about this, enter the door, raise to the roof space, lower down under the beam, raise to the roof space, lower down under the beam, raise to the roof space, lower down under the beam. I became very good at this and zipped the loads off the truck in great time.
The foreman who did not think I was the best employee working there told me on several occasions " It you break just one unit I will have you sacked". I continued to do the job and he continued to warn. One day the boss was out and a truck arrived, I walked to the forklift only to be ordered " leave it to me I don't want any shattered units.
He is the foreman so I left him to it, his first load took him 25 minuets it normally took me 5 minuets, 19 units safe. the next load fell off and shattered. Will he suggest to the boss that I did it, No the boss saw him shatter the next 19 units. But the boss did reprimand me for allowing the foreman to drive the forklift.
I quit the job.
