Human Resources relates to people management, this can include staff recruitment, payroll, and policy management. This job type is suited to someone who is highly motivated by getting things done the right way. You are someone that operates by the idea 'if it's worth doing, it's worth doing well'. HR departments need to be up to speed on policies, along with payroll related policies such as superannuation and taxation.
Since HR is related heavily to people, you will need to be good at relating to people, and be driven by being open and responsive to the needs and welfare of others.
