Applicability of Labour Laws to Schools
Schools do not come under the Shops and Establishments Act as they are not shops or commercial establishments. This has been determined by many court cases. However, you need to check the Shops and Establishments Act of your state to see whether it applies or not.
Application of Other Acts
The Payment of Gratuity Act, Employees' State Insurance Corporation (ESIC), and Minimum Wages Act apply to schools as well. Minimum wages will apply if schools and educational institutions have been listed under the schedule in your state, and the minimum wage is notified for them.
Nevertheless, the courts have declared that teachers are not employees or workers as defined by the law. Therefore, minimum wages, gratuity, etc., do not apply to them. Please refer to the judgment at
