Employment contract termination not time-limited; employer may terminate based on persistent valid reasons until they lose relevance.

The Supreme Court dismissed the employee's appeal to reinstate her employment after the employer terminated the contract due to long-term absences disrupting court operations. The court found that while the employee's health improved slightly in 1998, the reason for termination remained valid as the absences continued to cause organizational difficulties. Consequently, the court ruled that the employer's decision to terminate was justified and did not lose its legal effect.
