I was getting paid that to do that job 16 years ago. That's the trouble.
And it was only OK money then. Better if you hammered the overtime. Not good money by any stretch of the imagination.
It's alright if you're living in bedsitland and haven't got anything to spend your money on other than drugs and techno, but you ain't getting far on it.
But, again, being jobless - money's money, isn't it? You have to start somewhere. I'd love to have gotten paid £20/hr for that but it's not gonna happen, sadly. And sitting on your arse when jobs are available and complaining there aren't any jobs available because you don't want to get off your arse is something I find baffling (not you in this regard, obvs).
And it's decent money for us as we're used to not live with a lot, so to say. So out of the, hypothethical, £240-300 (if you do overtime, as you say), someone with a family back home can send half and still be good enough for food, rent and the likes, as he's not gonna live exactly centrally.
Having worked in a warehouse I'd say that is a load of rubbish. The warehouse was roughly 50/50 split of immigrants and natives, nearly all employed via an agency. The immigrant workforce had hard workers and slackers just like the natives. Some of the eastern European workers used to make monkey noises at the black workers, but I wont use that to say all eastern European immigrants are racist and all native Britains aren't. The only people ever caught stealing stock from lorries were immigrants too, but again I won't make lazy generalisations about that either.
Not in Amazon Dunfermline, which I used as an example (granted, not really said it though, did I? /facepalm). Mostly Polish and a few Romanian/Bulgarian/African/refugees. Not that there weren't Brits, but it'd say it was far from 50/50 for us. Only the higher ups were Brits, directors and the a few of the management/leader staff.
Also this was the most Polish people I've seen in Scotland ever, as I think before working there I'd only seen about 10.
And they/we steal more, even if everyone does, it's the temptation isn't it? Most notorious for us was, I believe, a guy that had stashed £3k of hard drives and the likes in his locker, and he was British lol only guy caught stealing off lorries was also an immigrant, but Italian... damn Italians ffs!
Point of what I said was to point out people not wanting to do a job, which is what I saw with my own two eyes. Clearly, your experience was different, and the warehouse was also probably smaller (guessing here obiously). I've also heard/seen many people say stuff like "I don't want to work in a warehouse when I can claim benefits, eff this job" in a really serious manner/conversation, so there's that.
