- Saying nothing about it, but "secretly" moving the team to another country by changing the manager and director, and not hiring anymore in this country, even when team members quit. It took awhile but I figured out that the plan was to let natural attrition take over and for every person who quits from here, hire their replacement there.
- Different company: after being acquired, the acquiring company communicated for eight months that no changes in staffing would take place, and that once the acquisition closes, everyone will be put on exciting new projects and a new bright future will emerge. Then, after the acquisition closed, laying off a third of the company immediately. Another third chose the exit soon after. Eventually, the company died.
- Third company: after being acquired by a large competitor, the director of technology for this third company promised them a new product for four years. I'm led to understand by those closer to the situation than myself that this director then proceeded to coast on vaporware demos for those four years, claiming the need to "pivot" or "reboot" the product as necessary, and promising more and more pie-in-the-sky fantasies until finally the gig was up and he was fired. That subsidiary also officially closed its doors eventually.
Just a few from my own experience!
