Labour Law Conundrum: Workmen's Comp and the Employer's Liability

Abhi 3 din mein exam hai aur main abhi bhi yeh nhi samjh paa rha.. yeh kya hai ki employment exchange kya cheez hai, Workmen's Compensation Act 1923 kya karta hai aur Employer's liability mein kya hai difference? Main socha tha ki Workmen's Comp koi bhi factory k company mein lagata hai, lekin abhi bhi nhi samj paa rha. Employer's liability ka koi specific definition nhi hai aur Employment Exchanges Act ka kya connection hai Workmen's Comp se? Main socha tha ki yeh dono separate cheez hongi lekin abhi nhi samj paa rha. Koi bhai/Behen ka madad karein, please.
