for govt servants creamy layer is decided by post and not by income

2) as per the Central creamy layer criterion II & III dated 08.09.1993 only the sons and daughter of following “government servants” will be treated as creamy-layer.

(i) Parents, either of whom is a Group-A officer.

(Direct Recruitment)

(ii) Parents, both of whom are Group-B officers. (Direct Recruitment)

(iii) Parents of whom only the father is a Group-B officer and he gets into Group-A at the age of 40 or earlier.

3) you would be entitled to OBC NL certificate

You would still be entitled to OBC NL certificate

Direct recruit Gp-B officer and have not become Gp-A officer in the age of 40 shall not under non creamy layer;

Thus you may come under OBC NCL for the purpose of getting the concession/privileges under this category.

Though my mother was directly recruited as class C,now she has been promoted to Class B.So, now both my mother and father are Class B employees.So what will be my OBC status? creamy or non creamy?

The status of government employees at the age of 40 years or if they were direct Gp-A officers, shall determine the status of OBC NCL
