These practices and policies include, for instance: Conducting job analyse Planning labour needs and recruiting job candidates Selected job candidates Orienting and training new employees Managing wages and salaries Providing incentives and benefits Apprising performance Communicating Training and developing Building employee commitment Also Human Resource Managers should know about: equal opportunity and affirmative action, Employee health and safety, Grievances and labor relations. (Management Concept & Practices) Human Resources Management in The Organisation If we want the Human Resources roles fulfil effectively, the top manager of the department should be at the top of the organisational hierarchy, with line authority to the chief executive officer. The top manager and staff of the Human Resources Department are increasingly expected to be functional experts, capable administrators, business consultants, and problem solvers. Specialised human resource expertise is also important.Particularly now in combination with business knowledge and perspective.
