I'm afraid I take issue with this argument as regards to bricklayers, they were not all like the cheery Auf Wiedersehen lot portrayed on TV, indeed bricklayers could earn some great money, London and the likes but when winter came it was all evened out over the year to be nothing extraordinary in terms of pay for the slog they had to endure. Plumbers and electricians were different as they could work indoors, but bricklayers were open to the elements so rain, snow, ice, even heavy frosts meant 'sorry lads no work today'. And that meant them going home with no pay as many were changing over to self employment instead of 'on the books', at one time bricklayers were also plasterers, tilers (wall and floor not roof tilers) so had inside work, as long as the temperatures didn't go too low, it was plus 2 and falling then worked stopped.
Many brickies went to work in Germany but the contractors were actually Dutch and I had a few friends who having done the work were then ripped off as the agents had disappeared with the wages so our lads were broke and in a foreign country, literally up the creek without a paddle. I myself never fancied working abroad as much as I never fancied going self employed despite 'poachers' trying to get us to sign contracts to work where we could double, or even treble, our level of pay at the time. But even now, I was in London last week, the level of building there is unbelievable to what is going on in Hull so yet again I suspect that the South is where the money is yet again, I'm glad that I do not have to chip ice off a wall before I could continue to build on it any more, and yes we had covered the wall with hessian sacking before anyone says.
