When I was in college, I worked as a night security officer for the first while, and my job involved walking around campus. After I quit, I still remained as a student and was on campus hundreds of times. But I never went to the security office.
At another place, I was a sales manager and then started working for a vendor, so I went back many times, but it wasn’t to visit people.
Yeah, I retired late last year and have been back twice in the several months since. Why? Well I live ten minutes away from my former work site and they have a sweet, sweet treasure worth visiting. A generally empty dumpster just begging for old broken chairs or other similarly annoying to dispose of bulky items.
Very technically I shouldn’t have that access of course. But I have an open invitation from my old boss, their boss and my former co-workers. So I call ahead to verify it’s cool, drop off my item(s) and wander in to briefly say hello and shoot the shit. I am not outside-work friends with any of this last set of co-workers, but I was friendly with all of them except the replacement I never met and it’s a small crew at a remote site.
Of course I do not expect to return often, but it’s a convenient way to get rid of large things every so often.
I have lunch occasionally (about once a month) with an ex-coworker. I did so today. After lunch, I visited some of my old workplace. They recently remodeled (went from 1 floor to about half). I didn’t go in the work area, just reception and some of public areas (the part we used to have – even some of the meeting rooms are still there and have the room names on them)
I was an employee at 6 companies, 2 of which still exist. The rest were taken over, mostly multiple times. After the last of these I worked as a freelance consultant in medicines licensing, but with close links to a consultancy group (kinda pseudo-employee, but I was simultaneously working as a true freelancer). They were also taken over multiple times, but I hung on until I retired (by choice).
The pharma industry is pretty incestuous, and as a consultant I went back to two of my former employers to work on projects (many years later in both cases). You want to know how incestuous? Back at employer #1 I was working with someone I knew from employer #2; and back at employer # 4 I was working with someone I knew from employer #1.
But more interesting than that – at least to me - Is what happened to employer #1. The company was based in an old country manor, a listed building (ie, under a sort of preservation order) There were various other temporary or permanent buildings to cope with overspill. When that company got taken over, the manor house was torn down and replaced with a huge glass and steel palace. Now, I was part of an inter-company group which met regularly to discuss developments in our field, and we took turns to host - so I got to go back to that site on three occasions. The only thing that remained from the site I knew was a single ornamental fish pond.
I have not, but only because the places I have fond memories of are far away, or at least, not in the same area where I am now. I’ve had several jobs in my career that I have very dearly loved, and I have indeed visited those places virtually, via Google Maps, but not IRL. One of those employers was a large corporation,* so there are actually many different places that I have fond memories of, most of them in the US.
* Yes, boys and girls, it’s possible for a large multinational to be beneficent and paternal. It’s rare, but it happens!
