Why Labour Law is a Recipe for Disaster

Abhi toh main toh soch raha hoon IPC aur BNS mein kya fark hai aur yeh sab labour laws ke rules dekhne mein busy hai. Kya ye log soote hain ya phir koi labour ka kanoon nahi leta. Bas yeh hi nahi hai, abhi toh maine read kiya ki koi bhi company 12 hours ka shift nahi de sakti, lekin agar woh karte hai toh woh employee ko 20 hours ka overtime de sakti hai. Bas yeh na kijiye, main toh confused ho gaya hoon. Abhi toh CLAT mein labour laws ki koi bhi question padhne ka maaamla nahi hai, toh phir yeh sab kya?
