In this case, ability is one of the criteria for employees' job performance to reach the expected level.

When an employee can abide by the law, be punctual, pay attention to clothes, abide by all the rules and regulations of the enterprise, and cooperate with his superiors to carry out his work in an orderly and excellent way, he will certainly be appreciated by his superiors.

On seniority, on the surface, it only looks at seniority, but in fact it is a combination of seniority and ability. After obtaining the qualification that can be promoted, whether it can be promoted depends entirely on the assessment of its work. This system recognizes the value of employees' experience and gives everyone an equal opportunity to compete.
