Understanding the Minimum Wages Act
It's very simple. The Minimum Wages Act was created to prevent firms like yours from exploiting employees/workers. Just because they need experience does not mean you should pay them below subsistence levels. If they are not adding value to your job, then why hire them?
In any case, there is no option but to pay the minimum wages, preferably by cheque. If you pay in cash and the employee claims you haven't paid, then you have a significant problem on your hands.
