As you have not mentioned the employee strength, I have not considered that aspect. The applicability of certain labor laws is based on the number of employees. Some of the commonly applicable labor laws could be:
1. Employees' State Insurance Act
2. Employees Provident Fund & Miscellaneous Provisions Act
3. Maternity Benefit Act & Kerala Maternity Benefit Rules
4. Payment of Bonus Act
5. Payment of Gratuity Act & Kerala Payment Of Gratuity Rules
6. Industrial Disputes Act & Kerala Industrial Disputes Rules
7. Minimum Wages Act & Kerala Minimum Wages Rules
State-Specific Acts Applicable in Kerala
The following state-specific acts are also applicable:
8. Kerala Industrial Establishments (National & Festival Holidays) Rules
9. Kerala Contract Labour (Regulation And Abolition) Rules [If your company employs contract labor]
10. Kerala Industrial Employment (Standing Orders) Rules
11. Kerala Labour Welfare Fund Act & Rules
12. Kerala Shops And Commercial Establishments Act & Rules
13. Kerala Panchayath Raj (Professional Tax) Rules
14. Kerala Municipalities (Professional Tax) Rules
Thank you.
