I am
at the idea of someone going into HR because they like the power aspect of disciplining people!
HR generally has very little power at all. HR don't do the disciplining. Management say we want to discipline this person, HR advise how to do it. HR don't as a rule conduct disciplinary hearings, they attend and advise.
If HR think the person shouldn't be disciplined, management can say no. If HR think someone should be disciplined, management can say no. Good HR people give good advice and can influence managers effectively to take the best decisions when it comes to disciplining (and everything else), but it's influencing other people's decisions, not exercising power.
If you want power when it comes to managing people, being a line manager and progressing as high up as possible is the way to achieve that.
There is a lot of 'negative' stuff in HR, yes. But being able to influence managers to take the best decisions possible and to conduct that stuff in the fairest way possible is a positive to that aspect of the job.
Helping managers get the best out of their staff is a rewarding thing to do, and that happens in loads of ways, from day to day performance management guidance to learning and development initiatives and practical team management tips. Encouraging them to have more of an open mind when it comes to recruitment and promotion (and seeing that pay off) is good. There's loads of good stuff.
I've not worked 'in house' in HR for more than 10 years now though. I moved into self-employment as an HR consultant for small businesses which I found more rewarding than working in house for a variety of reasons. Now I do very little of that either and instead support other HR professionals doing it, but I keep a few clients to 'keep my hand in'.
In terms of getting in HR it's usual to go in as an HR administrator-type role and work up from there, so having some good general office administration experience is a good start.
Experience managing people yourself is I think a fantastic thing to have as an HR person - as you climb the HR ladder I think it's hard to advise managers with credibility about how to manage their teams effectively if you've never actually done it yourself. I managed retail teams before going into HR and although I didn't enjoy it at all, I have no doubt that 'on the ground' experience of managing staff in an operational environment was a very valuable thing to have obtained before moving into HR.
