Your housing society will come under the definition of shop or commercial establishment and the provisions of your State's Shops and Commercial Establishments Act will apply to the only one employee employed by you. If so, you will have to show that he works only for 8 hours a day and he takes care of the houses/ flats/ apartments during his 8 hours duty and is allowed to take rest for the remaining hours of the day! Otherwise, it will become a problem for you because, you are not subject to engage a person for 24 hours; whether he works or sleep and only sleep, is your matter and if he is sleeping throughout, it is open to you to initiate action against him including dismissing him from service on the charges of sleeping while on duty. But the duty hours should not be 24 hours even if he has no work to do! Moreover, taking care of housekeeping, cleaning STP, ensuring security etc are the work assigned to him and that seems to be more than sufficient for a single person to handle. And it is not convincing to say that a housing society has only one employee.
