> "Non-regrettable" attrition means either that the person was fired or laid off. Since the post says Automattic didn't do layoffs, that means all of that attrition took the form of being fired because of performance problems.

> If 7% of the company exited the company in a year because they were fired -- which seems quite high to me -- then even if you don't call it a layoff, it has many of the same characteristics as a layoff.

In my experience, this will have a way worse effect on morale than layoffs and will trigger regrettable attrition, as the smarter people in the room realize that you're always one reorg away from having a 'performance problem'. Sad.
