Dear Colleague,
Hope you are meaning, update and amendments on labour laws. ( Statutory compliance update is no where available, which you need to only check on your own against required compliance requirements)
If you want to understand the updates on the Labour Laws, you may visit and check in the Labour Ministry Govt of India website, State Government Labour Dept website / PF & ESI Portal.
You may also subscribe for good Journals like Labour Law Reporter which will bring you all updates then and there.
