This document discusses different types of changes in employment status: promotion, demotion, transfer, and separation. It provides details on the criteria and approaches used for promotions, as well as the reasons behind demotion, transfer, and employee separation. Promotion generally involves reassignment to a higher position with increased responsibilities and pay. Demotion is a move to a lower level job with fewer skills and reduced status. Transfer involves reassignment to a similar job in a different unit or location. Employee separation can be initiated by either the employer or employee and terminating regular employees in the Philippines requires following specific governing laws.
