What was "The Incident" at work that caused an exodus in the work force?

I was working for an Australian company, that was bought by a big (F500) American company. Actually they bought over 200 companies globally to become what they were.

After the dust settled, the American corp started talking all sorts of stupid American stuff that would never fly in Australia. For example ALL Aussies have the right to 4 weeks annual leave, and 2 weeks of sick leave per year. They wanted to change that to 3 weeks and NONE! (again would never have happened, legally, but damage was being done..)

Staff started to leave.

Next thing was then global conferences at stupid times of the night/morning with staff that were not typically the type to take meetings AT ALL. (Not upper or middle management, I mean workers and supervisors) This was around 2015, way before anything we are more familiar with today.

More left (work/personal life balance)

And finally was all the stupid buzzwords and never ending general shit that we just didn't care about. "Bi-weekly" (ambiguous globally and simply should not be used. It's either fortnightly or twice a week..) Not to mention the plethora of other buzzword shit like "holistically engaging in resource-maximising virtualisation" and bluesky or "data-only sales" (we made manufacturing equipment ffs!!)

Middle management started to walk, it was becoming a rolling stone covered in moss.

Then when there was a bit of a market shift and the economy went down (and therefore the American company took an EBITA hit, they laid off 20% of the staff). This led to further insecurity in the company and about 30% of the rest of the workers said fuck it and left. What do you expect when they are assembly/production or electricians etc who can get more stability from working out of a van and a mobile phone.

They managed kill themselves and even drop out of the F500 list!
