Understanding proposed labour codes: Reform or cause for concern? The labour ministry is formulating relevant rules and regulations to implement the four new labour codes. The four labour codes enacted by the Parliament in 2020 are set to be implemented soon. According to Labour and Employment Secretary Apurva Chandra, the labour ministry is formulating relevant rules and regulations to implement the four new labour codes in the next few weeks. Once the rules are notified, the codes would come into effect. The government introduced the codes with the aim to streamline and simplify the country's existing and overlapping labour laws. Since the subject of labour comes under the Concurrent List of the Constitution, there were hundreds of state and central labour laws.
