Re: Lies, damned lies and ...
Well, of course. If you were hired for a fixed-term contract with an employer with an AAA credit rating, wouldn't you try to carve out a permanent niche for yourself?
Some of them may not. The best and the worst, probably not. But the solidly-average employees - once they're in, they're in to stay.
Everyone who's ever devoted more than ten minutes' thought to the question always knew that Brexit would be horrendously inefficient. If only the Remain campaign had thought to mention that fact... but come to think of it, it probably wouldn't have made that much difference. The Brexit referendum was essentially a rerun of the Scottish independence referendum a year earlier - the issues were much the same and so were most of the arguments, except that the Scots actually did mention this issue, and it was still a damned close-run thing.
As I wrote at the time: "There's only so long you can go on treating voters as idiots. Even if they demonstrably are idiots."
