I am to be fair hugely scarred by my own experience of her recently. My husband died and we had both worked there in senior positions.
Without hijacking or going into it too much, she was awful: ringing me up pissed late on a Saturday night days after it happened, making suggestions for the funeral and then not listening to my response when I said 'I'll handle it.' Then messing up H's pay and not admitting it (trying to explain it away as 'policy' when it clearly wasn't). Final straw was when she sent me a formal letter the week after the funeral implying I had gone underground and talking about my personal legal affairs around my late husband's estate (mentioning his life insurance, which is nothing to do with the firm). Just awful. I rang the CEO (my boss) in tears and she got a bollocking and apologised but it really upset me.
Prior to that there were other blunders but these affected me less personally.
As she is Global there isn't that much I can do although I am discovering I am not alone in my view of her.
As I said, I know a couple of very senior HR people who are friends and I know they are excellent at their jobs. Part of the problem at our place is that what we do is quite specific and the current HR head has no real understanding of it, and so she ends up making suggestions or decisions that don't work for us.
I think we need to find an HR talent who specialises in our field; who knows employment law and policies inside out but who also 'gets' the field. Anyway I had better belt up now as if she is reading this she will have a strong suspicion I am talking about her!
