Minimum Wages will not get revised every year but there will be periodical change in the variable dearness allowance. Therefore, if you want to know the minimum wages of employees in shops and commercial establishments of Kerala you have to refer the then prevailing notification and fix the DA according to the then prevailing index number. In Kerala unlike other states, VDA changes every month based on CPI.
Now, if you are interested to know the current minimum wages which was notified in December, 2016, please find the attachment.
Also please find the notification of minimum wages as applicable to Security personnel in Kerala. Please see that this thread was started in 2009 and in 2014 I had sent an attachment of minimum wages of security personnel and this has been replaced by the new one attached now.
