Hi,
If you want to become good HR person, be a Business Partner, post your HR representative in Line function and be a Advisor, Strategic thinker, involve in the business meeting and advise the impact on manpower, concentrate on soft aspect like behaviour, attitude and how that liks to rentention and this contributes to the bottom line interms of benefits. If you talk about hard aspect like recruitment, payroll, admin etc. they will say this can be outsourced, most big organisations are success not because of the money power but because of people and that is our strength and we have to take care in a nice and professional way... HR can make the difference if you plan it properly and if you get your top officials recognistion and blessings that is lies on you
