Many companies require staff to leave immediately upon tendering their resignation - including non-IT companies like mine. You tender your resignation and all your access is removed within 24 hours. I work for a utility company that manages what the Department of Homeland Security classifies as 'National Critical Infrastructure', i.e. generation plants, transmission, distribution, metering, and FERC mandates your access is cut off ASAP. You'll get paid for your last two weeks, but you can't do anything.
My friends in health and finance have said they have similar mandates. Us folks in IT can mess up too many things to be granted continued access. We need to be cut off.
Even prior to working for a utility I've worked at places where people were escorted off the property by security when they tendered their resignation. Their personal items in their office would be packed up and shipped to them. This has been going on for decades.
There was one job I had where I was so well-liked and we had considerable mutual respect that I was still granted visitor access to the facilities, meaning I required an escort. I no longer had access to any of the systems, but I could guide those who did. That worked out really well, too. Heck, they negotiated an extra six weeks instead of two and paid me 50% more to boot! That made a helluva impression at my new company! Then I got a great sign-on bonus at my new company! Boy, those were the days!
I have almost 30 years in tech and thankfully have never run across that. But I can see how that could be a thing for other companies/industries.
Every place I have worked I have given 3 week notice, and every potential employer has been ok with me starting in 3 weeks (except one).
The one exception was a company that balked at my request to start in 3 weeks in order to give my current employer time. They countered with "Well, take it now and start immediately, or leave it. You must not be serious about working here." I countered with "You are probably looking to hire people with no sense of responsibility to their current employer". Bullet dodged.
I have quit before I have started. I accepted an offer from a company (after being jobless) but my interaction with their HR the day before I was to start was so rude and combative that after I left, called my future boss there (who I really liked) and told him I was rescinding my acceptance.
I then grovelled back to another job whose offer I had turned down (and they re-made the offer). It all worked out.
