The reality is in these people's wage packets
Everything is temporary and unsustainable to a point, bankers bonuses? Did the rich turn their nose up at them? Anyway If/when rises come to an end the reason will probably be through poor economic governance not through the act of Brexit. Anyway the length is not the whole issue, the worker/employer correlation change was desperately needed. Yours is a rather bizarre argument.
More rights are obviously welcome but sky high unemployment has always been the main enemy of job security. We both live in areas blighted by mass unemployment. Thatcher used it in the 80s with an unemployment rate of 3mil plus. Employers knew they have a large pool of workers to call on and use it accordingly to slash pay and conditions.
An awful lot of political commentators on both left and right predicted an upturn for the lowest 20% of workers in mainly manual lower paid occupations. Cummings being one of them. It really wasn't a suprise.
