I heard that LGW / Crawley had 100% employment is that true. i.e. if you want a job there are plenty there
I am not quite sure what you mean by that, it seems to be contradictory. My understanding of 100% employment would be that everybody of working age is employed, and every job is filled, which is demonstrably not the case if you walk around Crawley.
From what I've seen of that place, most of its residents prefer to be pregnant, getting pregnant, making someone pregnant, on the dole, at the pub, mugging, walking around with tiny babies, stuffing their bloated bodies with McDonalds, or shopping at the Pound Store.
I would imagine therefore that anyone who actually wants a job, has two hands and feet, two eyes and a nose, and an IQ above 60, can probably find one quite easily, as there isn't much competition.
Edit : To avoid giving offence to Ppruners who live in or near Crawley, the above description only applies to the unemployed/unemployable, since the others are working!
