This discussion addresses the possibility of rejoining a Public Sector Undertaking (PSU) after a technical resignation to take up a state government post. The core issue is whether 'technical resignation' rules, which allow for continuity of service benefits in central government roles, also apply to PSUs under the petroleum ministry. Guidance suggests that if the original resignation was submitted correctly, specifically requesting it be treated as technical due to taking up another government appointment, rejoining may be permissible. Consulting a local lawyer specialising in service matters is recommended for personalised advice and assistance.
