Not sure about her record, but the entry on Wikipedia says her mom works/worked at UNAM (one of the most famous Mexican universities). She was hired there and received some awards. Hard to say, but it has the smell of nepotism at the very least.
Her family mostly seems to associate with middle class directors, politicians and faculty. Definitely more privileged than the average Mexican, not much different than a US president. I’m guessing the policies will be what you’d expect with maybe a spin for the plebeians to think she’s on their side (again, much like the US).
This could only lead to a hostile work environment. The process and checks in it is what needs to be questioned. If it came out it was an executive bypassing process, then yes. Otherwise the process can be updated and improved. It also needs to be publicly disclosed why it happened given the nature of the claims.
