Dear BMCRI
It is difficult to give a proper answer without having details of the contract, period and nature of work.
In general, if you have a contract to work for a fixed period, it will not give you a right to claim permanency. But at the same time, the nature of work and the provision of the Standing Orders may change the answer.
If the employment continues for long after the contract is over, then the employee can claim that he is made permanent (by action as he is being treated as a permanent employee) or that the original contract was a sham. That depends again on the contract, nature of work and other factors.
Again, if it is a one off or a regular feature among many such employees, will decide which way the courts will go.
