Which one among the following defines flexi workers in India?

In India, flexi workers (or flexi staff) are defined as formal contract staff employed through organised staffing/contract arrangements via third-party staffing companies. They are on the payrolls of staffing companies but work at client organisations, enjoying statutory benefits like PF, ESI, and gratuity. This is distinct from informal labour, gig workers, or unorganised sector employment. The Indian Staffing Federation defines flexi staffing as a tripartite arrangement involving the staffing company, the client company, and the employee. Flexi workers contribute to formalisation of the workforce and provide flexibility to employers while ensuring social security to workers.
