An individual who joined a Public Sector Undertaking (PSU) from a central government department in 2010 is seeking clarification on why their previous pay was not protected. Despite numerous attempts to resolve the issue, the PSU HR only confirmed in 2018 that pay protection would not be granted. The discussion highlights that while the Department of Personnel and Training (DoPT) does not mandate pay protection for central government employees joining PSUs, some PSUs may offer it through internal provisions or negotiation. The user questions the perceived discrimination, noting that PSU employees transferring to central government roles typically have their pay protected.
