I am glad your son made it through. Sometimes its better to survive, sometimes its better to be the first one out?My son works for Tesla. This is the third layoff since he started a few years back. Luckily he survived this one again.
Many employees were not notified ahead of time. There was a 1.5 hour line of cars at the plant gate and you found out if you were laid off by the guard denying access through the gate.
Years ago I worked for a big company that seemed always to be laying people off. I think they did small batches so they could stay under the reporting requirement. Anyway the first way you knew is you showed up and your phone didn't work. Some people (not me) thought it was funny to occasionally unplug someone's phone
