A more thorough explanation: Seniority status refers to the length of time an individual has been employed by a company or organization in relation to other employees. It is often used to determine various rights and benefits, such as promotions, pay increases, and job security, based on the principle that longer-serving employees should be given preference or priority over newer employees.
Example: The employee was promoted based on his seniority status within the company, as outlined in the collective bargaining agreement.
