The issue of 12-hour shifts in the security industry
There is a widespread practice in the security industry of 12-hour shifts, as well as continuous working without weekly offs. This is partly for extra earning or for accumulating extra offs to be availed at the convenience of security guards. Legal provisions do not support this practice at all, yet it is done clandestinely and in connivance with all. However, it is inhumane to subject anyone to continuous 12-hour shifts for a considerable period of time. The natural consequence is that there will be slackness and dilution in standards of duty done, as it is impossible to remain vigilant and alert for such a long duration, especially for days together.
Compensation for a 12-hour shift
As for your query regarding compensation (CTC) for a 12-hour shift, it depends on your compensation mechanism as to how you are paying for the extra 4 hours of duty. Is it at double the rate or through some other means? As professional HR people, we should not encourage such practices that are blatantly illegal and inhumane.
