Thats not true, I didn’t even have a passport (and I still don’t have a drivers license) for many of the jobs I had in the UK. UK society does not demand that you have a passport per-se, but there’s very few functional photo ID documents available outside of a drivers license or passport- and getting by without those is annoying but totally possible. I used to “prove” myself with bills addressed to me, and having a bank account- since, again, neither passport nor drivers license. Now, getting the bank account was difficult, required a guarantor. But jobs themselves had no requirement, and I could give them someone else’s bank account details I guess. Same is true of the national security number, which is probably what you meant that the employer must get; that “string” informs the government when you pay tax and therefore you need to be able to work to have one- except there’s no way of proving you’ve supplied the right one: the NI card even says on it that the card itself is not proof of ID.
