My schools have been razed to the ground and 90% of the jobs I can remember are now located under housing developments. I sometimes go somewhere a think 'oh, I worked round here once, but tbh, the 1994 - 2005ish period was one of small children, zero security jobs and temping several things at once to keep a roof over our heads, so it's all blurred.
These are the vaguely memorable ones
Demolished office block now housing
Demolished, now a PRU
Demolished office, now housing
Demolished council office, now hole in ground, employer defunct
Demolished workshop now housing
Temp (demolished) on industrial estate
Temp, temp, temp, temp, temp, temp, temp, temp, agencies long gone and sites demolished, places demolished for housing, car parks and a Sainsbury's petrol station, housing, underneath a hotel that's now been demolished for shopping and housing
Hospital demolished and housing
Hospital off site clinic now a supermarket in its place
Hospital, closed, through defunct agency, becoming housing
Can't even remember how many bookings and sites through that place
Building still there, owner dead 20 years
Organisation closed - guess what's there now?
Building might be there but owner emigrated for retirement
Hole in ground whilst a tower block mixed development goes up
Pub been through about 20 owners and four breweries, some of whom went bust
Address is now technically in the middle of Lidl
School closed five years ago, nobody left, probably going to be housing if it's not razed to the ground by trespassers first.
My only truly verifiable work history (as in same location) is the last 5 years.
I get annoyed when I have to deal with these US reference places. No, we do not have records of people five sites and 45 years ago, nor is it essential for the applicant to know the exact day in 1972 that they were processed as a leaver, so there is absolutely nothing to worry about as I don't always have an exact date (if any at all, we didn't ignore GDPR and transfer paper documents including hundreds of thousands of register marks to computers when we finally got one around 1999 either, but it'll be some time between the last Friday in June and the first week of September. If I have a scratch around in a basement I might find a minidisk or DAT that could hold our earliest computerised info, but we've got nothing that could read it if it's not completely defunct - and it's still about 30 years too new.
