A human resources department isn't just a team of experts who know how to manage people: it's a team of experts who know how to manage the people in their particular company. Although every successful HR team is unique, most HR folks use similar tried-and-true strategies for keeping things running smoothly. For example, many check in with employees regularly to discuss their goals and offer them development opportunities. Some gauge employee sentiment by observing behavior in the office, and some take managers out for coffee to discuss leadership or succession questions. Whatever strategies they employ, the HR activities that most successfully address problems share one common feature: interfacing with people.
