Hi,
If you have a premises/building, where you are getting some work done through a contractor.
Whatever employees are hired by your contractor are covered under the contract act, this contractor must take a licence from the labour de partment for hiring contract labour and work on contract by paying necessary fee etc.
Also, your co. being the employer must have the licence to hire contractor for any kind of work whether security, housekeeping..
I hope this is clear now.
regards,
Umesh
