Explanation
The classification is based on the nature of employment as defined in the textbook. Self-employed workers own and operate their own enterprises (saloon owner, handloom weaver, cold drinks shop owner). Regular salaried employees are engaged by an enterprise and paid wages on a regular basis with job security (cashier in SBI, nurse with 5 years of regular service). Casual wage labourers are casually engaged and paid on a daily basis, even if employed regularly - they lack job security and regular salary structure (rice mill worker paid daily, typist on daily wage basis, loading worker).
