Total Rewards program
TIER IV has introduced a Total Rewards program, a framework that supports employee growth, evaluation and motivation. Through this program, we aim to help every employee realize their full potential and contribute to our mission and vision.
-
A performance-driven grading system has been implemented to ensure flexibility and scalability. Based on the company’s core values, Our Principles, and key focus areas, four core competencies are defined, with expected levels of achievement established for each grade.
-
The system features dual-track career paths – management and professional tracks. Each path has clearly defined expectations for the competencies, scope of impact and roles required at every level. Promotions and demotions are based on demonstrated competencies, with management track advancements requiring specific assignments. To evaluate performance adequately in response to the company’s business growth, a flexible, multi-level promotion system is used, allowing grades to be assigned independent of tenure or age.
-
At TIER IV, the purpose of evaluation is to foster the growth of each employee and strengthen their abilities within the organization.
Performance evaluation: Individual goals, including difficulty and weight, are set in alignment with organizational objectives, and individual performance is evaluated based on achievements.
Demonstrated competency evaluation: This assessment focuses on whether employees have met the standards of demonstrated competencies defined for their grade. This evaluation serves as a development tool, highlighting areas for improvement necessary for promotion to the next grade and provides employees with insights to support their ongoing personal growth.
