Dear Friend,
In Maharashtra, the state government has formed a separate board to finalize the wages of the security guard board. These rates are applicable to all industries, but they are higher than the unskilled labor rate. Therefore, most industries file applications for guard board exemption. If they are unable to pay this guard board rate, they will then pay according to the state government's scheduled employment category rate or the rate applicable for the shops and establishment category.
In your case, if the shop act is applicable, you can consider the shop act minimum wages for security guards.
