As you all know that pay protection and pay fixation is different and applicability is also diferent in various department/organisation under Govt/PSU/Autonomous body etc.
Department of Personnel and Training has issued various instructions from time to time regarding protection of pay of candidates on their appointment to Central Government posts on Direct Recruitment basis. These instructions are broadly categorized in three parts as under:
A. Employees of PSU etc. on their appointment to Central Government.
B. State Government employees on their appointment to Central Government.
C. Central Government servants on their appointment to Central Government.
A Central Government Employee on his appointment to a post in higher level in different service or cadre in Central Government carrying duties and responsibilities of greater importance than those attached to the post held earlier by him on regular basis before such appointment and having a provision of probation period in new post, may during probation draw the presumptive pay of the post held earlier by him on regular basis if it is higher than the minimum of the Time Scale of the new post. He would also draw annual increments on such presumptive pay. However, it is to be ensured that during probation presumptive pay should always be greater than the pay of the new post after drawal of increment(s). Subsequently, on successful completion of his probation, his pay will be fixed under FR 22(I)(a)(1). Protection of Pay in the above manner should not, at any of these stages, exceed the maximum of the Level of the new post in Pay Matrix.
