Human resource management has four basic functions: staffing, training and development, motivation, and maintenance. Staffing is the recruitment and selection of potential employees, done through interviewing, applications, networking, etc. There are two main factors to staffing: attracting talented recruits and hiring resources. HR Managers must create detailed recruitment strategies and have a plan of action to put forward when recruiting. Next, managers can put strategies into place through hiring resources, by extending out to find the best possible recruits for the team. Recruiting is very competitive since every company wants the best candidates. Using tactics such as mass media can grab the attention of prospective recruits. Training and development is the next step and involves a continuous process of training and developing competent and adapted employees. Here, motivation is seen as key to keeping employees highly productive. This includes employee benefits, performance appraisals, and rewards. Employee benefits, appraisals, and rewards are all encouragements to bring forward the best employees. The last function, maintenance, involves keeping the employees' commitment and loyalty to the organization. Managing for employee retention involves strategic actions to keep employees motivated and focused so they elect to remain employed and fully productive for the benefit of the organization. Some businesses globalize and form more diverse teams. HR departments have the role of making sure that these teams can function and that people can communicate across cultures and across borders. The discipline may also engage in mobility management, especially for expatriates; and it is frequently involved in the merger and acquisition process. HR is generally viewed as a support function to the business, helping to minimize costs and reduce risk.
