That's pretty standard in tech. Most companies have this automated from either the layoffs convo or the email being sent.

Back in 2012 I was laid off in a very short meeting with my boss and HR. This was at 10am when everyone was in meetings, so I left a quiet office and entered the stairwell to leave. My badge got me on, but I was unable to leave. I spent 20 mins awkwardly waiting for someone to either pass by or notice so that I could be escorted out of the building.

I'm at Amazon now, and some of the stories of people losing access are horrible. Some layoffs coincided with RTO, with some people moving across the country (NYC to Seattle) only to be told once their life was packed up and being shipped away that, actually, there wouldn't be a job to move to. There were also stories of IT failures for people, and people basically breaking down in tears at losing their job, when it was only email downtime.
