Not true. All they need to do is bring in "their own" people and put them on a few key positions. These Nepo babies bring with them the wrong culture and manage a company to death.

The best people see these assholes coming a mile away and jump ship. They do not get replaced (cost savings on these expensive people is huge) or get replaced by new management with sub standard hires that meet their "yes man" corporate lingo buzzword bullshit standard.

This causes the next wave of talent to leave, the death spiral is in full swing.

All this can happen in a few months. The effects might take a while to show, but I guarantee, it is hard to recover from.
