Leadership is afraid of them. When I was there I had the same skip as some prominent “activist”. I’ve seen other people let go for poor performance pretty quickly but somehow this nutbag was spending all of his time on internal g+ and company-wide mailing lists where he bragged about how many people he reported to hr monthly among other things. All while doing fuck all for his actual work. Lasted 3 years before finally getting canned then sued
Doesn't sound as leadership were scared of them then. Dismissal processes for things that aren't gross misconduct frequently take a while as they go through various warning stages.
There were plenty of things that could be considered “gross misconduct” that I won’t go into. And as I said - same part of the org had people gone much quicker when just not performing.
