Contract staffing services are increasingly popular in today's business environment due to their ability to create an agile and flexible workforce. The workforce can be divided into contract, temporary, and permanent categories, with permanent recruitment involving regular payroll with defined job descriptions and remuneration details. Temporary staffing solutions are provided by staffing agencies and are ideal for short projects or replacing existing team members on leave. The gig economy and contract staffing trend have led to the on-call employment system, where employees offer their services for a fixed period.
