Does anyone know if there's any actual reason why you couldn't just get mates to pose as former employers? I did have one job where I had a slight falling-out with HR just as I left regarding the length of my notice period, but I also got on really well with one bloke who'd been my direct supervisor and who left just before I did, so now I just give "[hitmouse'sformersupervisor]@hotmail.co.uk" or similar as my reference for that job. And thinking about it I think my supervisor from the job before that is now retired so if I ever need to give references from that far back I think I'd give that supervisor's personal rather than work email as well. Anyway, both those people are genuine former supervisors/team leaders/managers I've had, but with me giving their personal emails rather than work ones, is there any way it'd be possible to tell them apart from mates pretending to be former employers?
Also, I still resent the fact that when I started a new job in 2017, they told me to give references covering the past five years, so I did and explained that I'd been on JSA for a bit in 2012-13, and they then insisted I had to go and get a letter from the job centre proving that I'd really been on benefits then, to show that I wasn't one of those bullshitters who pretends to be on JSA to make their CV look more impressive.
