100%. My last layoff was in 2011, but at that time they closed the entire office I was in at the time (50 of us laid off). We helped eachother find places to interview and met up once a week to have lunch. I ended up working remotely with 3 of my old co-workers.
When I was laid off, it was very comforting to rebuild community with others who were laid off at the same time.
We started a Slack instance where we:
* shared resources with each other
* complained and vented and healed together
* celebrated each other's new jobs
* continued the network for years after
