Minimum wages are published every six months for most Indian states. They vary by time periods: Jan-June & July-Dec or Apr-Sept & Oct-Mar. Most of the time, they are published with retrospective effect as the CPI index is not available on time. Therefore, as mentioned by KK!HR, I fully agree.
Observations regarding minimum wages
1. In most organizations, minimum wages are paid to contractual workers and, in some cases, to permanent workers in small organizations.
2. Some organizations pay more than minimum wages, especially to workers who have been employed for years. They review annually, so a six-month retrospective review is not required.
3. Some organizations pay minimum wages with a six-month review and retrospective effect.
4. Some organizations do not follow point number 3 but pay minimum wages from the month they receive the information, with no retrospective effect. Additionally, some organizations do not pay minimum wages at all.
My personal opinion is that contractual workers and permanent workers who have been employed for years should receive more than minimum wages (though not equivalent to permanent workers) by receiving an annual increment.
We all know the famous Maruti case when, for almost similar jobs, contractual employees were receiving 18k per month, whereas permanent employees were receiving 42k per month (as far as I can remember the figures). In my opinion, the contractual employees might have been paid close to 30k per month at that time when the organization was a very large industrial house.
