For five years, Ali had been toiling for his company. All of a sudden, the company told Ali that he was no longer needed.
Ali protested. Surely, he could not be sacked on the spot. His company said 'yes'. After all, he was not on the company's payroll. Unbeknown to him, the 'real' company which Ali had been working for all these years was a labour contractor. It was this labour contractor which is supplying workers like Ali to the company.
This is the new trend in outsourcing.
