Human resources gets a lot of flak from other departments in the company. Much of the good they do (administering benefits, for example) is invisible, while their less enjoyable duties (handing out pink slips) are right out in the open for all to see. Recently, a few companies have done away with HR altogether, replacing some functions with software that automates payroll and benefits, etc. But are workers really better off without an HR department?
How much does your employer know about you? If they're using "people analytics," the application of big data analysis to human resource management, the answer is: probably a lot.
