Not only that, look at the terms themselves.
If you (or your job) has been "made redundant", it means - quite literally - that they no longer have a use for you.
We call that "laid off" on this side of the pond. Quite different than just "laid", I assure you, and they're both different from "laid out", which might also involve lying down, but I always say, make love, not war. Lay offs are when a business needs to reduce its workforce. There are a lot of rules and regulations about how its done. The natural tendency is to get rid of the deadwood as cheaply as possible, but there are significant rules designed to keep things "fair". I've been on both sides of the lay off process, at least half a dozen times. One time we laid off my whole division, so I've even laid myself off.
. . . especially when I spend a LOT of my time looking up what the hell certain Americanisms mean because they're not at all obvious (John Doe? Really? You can't just say you don't know their names?)
Not to be confused with John Deer, John Handcock, Johnny-come-lately or Dear-John or just a plain John, which has several meanings, none of them particularly flattering, or even doughboy, although even you Brits ought to recognize that last one. And over here Johnny is just a friendly name for a guy named John, or sometimes any bloke.
Not to be confused with the Fifth Amendments, although truthfully I've never quite understood the difference between Parliament and Funkadelic. And lots of people smoke Parliaments, although that's probably NOT what P-Funk was smoking.
Do you *really* want to go down that road? At least NYC was laid out (mostly) by people who actually SPOKE English, whereas London, for instance, was laid out by blokes who spoke SPOKE A DIFFERENT LANGUAGE ENTIRELY. And they burnt the town to the ground every few centuries and changed everything, but kept all the same road names. I mean, have to actually LOOKED at a map of London? I bet there are tourists who've been lost in there for YEARS.
And by the way, you've got your own share of odd terms. Over here a sleeping policeman is actually a sleeping policeman!
Don't get your knickers in a twist or throw a wobbly. I'm not trying to be cheeky or even twee. We could argue about 'maths', 'plasters', amongst' , 'paracetamol', 'petrol' or a bunch of other words in inverted commas, last of all, zed, for heaven sakes.
Let's forget all that and just stay mates. And by that I mean pals and not any sort of hanky-panky. Sure, we had our disagreements every now and then, and actually burning the White House was a bit beyond the pale, but we've got your backs and you've got ours. US and UK, BFF.
