Dear Pankaj Gawli,
According to rule 62(4) of Industrial Dispute (Bombay) Rules 1957, Where a settlement is arrived at between an employer and his workmen otherwise than in the course of conciliation proceedings before a Board or a Conciliation Officer, the parties to the settlement shall jointly send a copy thereof to:
1. the Secretary to the Government of Maharashtra, Industries and Labour Department, Mumbai;
2. the Commissioner of Labour, Mumbai;
3. the Deputy Commissioner of Labour (Administration), Mumbai, or the Deputy Commissioner of Labour,
Poona, or the Deputy Commissioner of Labour, Nagpur; and
4. the Conciliation Officer concerned.
According to rule 58(4) of Industrial Dispute (Central) Rules 1957, Where a settlement is arrived at between an employer and his workmen otherwise than in the course of conciliation proceeding before a Board or a Conciliation Officer, the parties to the settlement shall jointly send a copy thereof to:
1. the Central Government;
2. the Chief Labour Commissioner (Central), New Delhi;
3. the Regional Labour Commissioner (Central); and
4. the [Assistant Labour Commissioner (Central)] concerned.
I suppose, you are from Mumbai. If your appropriate Government is central then you need to follow the Central rules and if your appropriate Government is Maharashtra then you need to follow Mumbai rules.
