Human resources specialists are responsible for recruiting, screening, interviewing and placing workers. They may also handle employee relations, payroll, benefits, and training. Human resources managers plan, direct and coordinate the administrative functions of an organization. They oversee specialists in their duties; consult with executives on strategic planning, and link a company's management with its employees.
HR specialists tend to focus on a single area, such as recruiting or training. HR generalists handle a number of areas and tasks simultaneously. Small companies will typically have one or two HR generalists on staff, while larger ones may have many devoted to particular areas and services.
