@mike what’s news this time?

The latest ultimatum that Musk has given employees has had them largely call his bluff and a huge number have chosen to resign

Recent departures have left multiple critical systems down to two, one or even zero engineers, according to a former employee who was familiar with the situation and spoke on the condition of anonymity out of fear of retaliation.

I was laid off from Twitter this afternoon. I was in charge of managing badge access to Twitter offices.
Elon just called me and asked if I could come back to help them regain access to HQ as they shut off all badges and accidentally locked themselves out.
