My employer in Kolkata deducts from my salary saying it goes to the labour welfare fund, is this legal?

Deductions towards the Labour Welfare Fund are statutory and permissible under the West Bengal Premises Tenancy Act 1997 enacted by your state legislature for the welfare of workers. Both the employer and employee contribute at rates notified by the state, and the fund is used for welfare schemes like medical aid, housing, and scholarships for workers' children in Kolkata. The deduction is typically a small amount per half-year and cannot exceed the ceiling prescribed by the state. The Calcutta High Court has upheld the constitutionality of such contributions as a valid welfare measure under the Directive Principles of State Policy. The employer acts as a collecting agent and must remit the deducted amount to the Welfare Commissioner within the stipulated time. You can verify the deductions with the Labour Welfare Board office in your district.
