Modern Morals: I hate the way my new manager talks to our team, it’s ageist and cruel — should I go to HR?

Question: I work in a large corporate where a new manager is trying to make a name for herself. She’s made a lot of changes over the last year and there’s a general feeling of anxiety on our team now. I wouldn’t mind if they were smart changes — but the processes she has introduced really don’t make any difference at all.
