INTRODUCTION
Organizational activities certainly have goals to be achieved, but the achievement of organizational goals cannot be separated from the performance provided by human resources within the organization [1]. Then it is necessary to manage human resources which can then be directed to achieve organizational goal [2]. So it is very important for companies to properly manage their human resources. Losing good human resources is a big loss for an organization [3]. Performance is seen as an employee's ability. Improving the performance of employees is important for companies to be able to survive in an unstable competitive business environment. Employees will be able to achieve maximum performance if they have high achievement motives [4]. Performance implementation is carried out by human resources who have the ability, competence, motivation and interests. How the organization respects and treats its human resources will affect its attitudes and behavior in carrying out performance [5]. Furthermore, performance appraisal has the aim of motivating employees in achieving organizational goals and in complying with predetermined behaviors, in order to produce the desired actions and results. [6].
Communication is one of the factors that affect the quality of employee performance [7]. Organizational communication has an important role in achieving an organizational goal. Communicating the vision, mission and values contained in the company verbally and also holistically, through activities and implicit signs. Elements of strategic planning and specific objectives need to be communicated at all levels at units, teams and individuals [8]. Often times, poor communication tends to make a decision wrong in the calculation. On the one hand, managers often misguide their subordinates. While on the other hand, subordinates also misinterpret what is directed by the manager. The basis for evaluating an employee's performance includes the quality produced, the quantity produced, working time and cooperation [9].
Leadership style also affects employee performance [10]. Leadership is the power to influence someone to do or not do something. For this reason, leadership requires the active use of abilities to influence others and in realizing the goals of the organization that have been set [11]. By applying the right leadership style, a http://ijstm.inarah.co.id leader can motivate group members to work optimally and can be used to assist in making the right decisions for problems encountered in organizational activities. [12]. Leaders can influence morale and job satisfaction, security, quality of work life and especially the level of achievement of an organization [13].

Employees need motivation from a leader in order to work optimally. If the leader is rarely present, the leader will find it difficult to be a role model for employees who become subordinates.
