Out of curiosity, which bucket does your case fall into? 1. You've had numerous bad experiences with HR across multiple companies, leading you to label "99%" of HR as rotten. 2. You've had one or two bad experiences with HR, and you're extrapolating from that and just assuming that 99% of HR is rotten. 3. Some other option I don't see.
Always had bad experiences with HR, with around 6-7 different companies. Talking with colleagues on the same industry and others found out that my experiences are not isolated incidents, but quite the opposite they've observed pretty similar things. And finally, have a few friends that work themselves into HR and outsourcing (for SAP & Oracle) so I can speak for that environment pretty well, it is a rotten field. And…
I fall into the bucket that hasn't had bad experiences with HR. They've been helpful when I've needed stuff, which has been minimal. They've been irrelevant the rest of the time. This has been the case at every company I've worked for.
