I've heard the phrase "turn a blind eye" and I'm wondering if there is a single word to represent this. In my context, I'm looking to describe something negative, for instance:

She turned a blind eye to her child's behaviour when she discovered he was bullying other kids at school.

 

A bad supervisor will turn a blind eye to his or her employees' poor work habits.

Neglect doesn't seem appropriate in some of these contexts. I've thought about using disregard or ignore but I'm not sure if they convey the same meaning/what the differences are.

Is there a single verb to represent this phrase?
