My company got acquired, and our CTO had basically been out of office for the best part of a year. Endless excuses that ranged from “I have a rare condition that meant I had to go to the ER or I’d die” to endless “family emergencies”. He once let slip that he’d stayed home during one of these to have a hot tub installed, so it was obvious he was grifting - all while gas lighting everyone working with him, and sending the company down the toilet.

We organised a mass complaint to HR, coupled with bad Glassdoor reviews AND almost all of the engineering department finding new jobs as we were all sick of working there. He eventually got let go, but it took a ridiculous amount of time for it to happen (about a year after the acquisition).
