Magis Young Achievers' Learning Center v. Adelaida P. Manalo

Summary

This case involves the employment dispute between Magis Young Achievers' Learning Center and teacher Adelaida Manalo regarding whether her employment was terminated through valid resignation or illegal dismissal. Manalo was hired as teacher/acting principal in April 2002 but submitted resignation in March 2003, followed immediately by termination letter from school. The Supreme Court ruled that the resignation was invalid due to lack of employer acceptance and subsequent filing of illegal dismissal case. The Court applied the three-year probationary period for private school teachers under the Manual of Regulations, finding that Manalo was illegally dismissed during her probationary employment without showing unsatisfactory performance. When employment contract terms are ambiguous, they must be construed in favor of the employee. The Court awarded backwages covering the remaining two years of the probationary period, establishing important precedents on probationary employment security and contract interpretation in educational institutions.
