The approval and recruitment process for fixed-term contracts is identical to that for permanent staff. In addition you must notify HR of the objective justification for the fixed-term so that this can be recorded in the contract.
Queen Mary University of London policy is that fixed-term contracts of any duration, including those of under a year, are appropriate only if:
Only the HR Department is authorised to issue fixed-term contracts on behalf of Queen Mary University of London.
The University generally uses fixed-term contracts for its research staff on limited-term contracts.
One practical reason why the University uses fixed-term contracts is that when the contract ends, the University has a streamlined process for reviewing the need for the job and, if need be, ending the employment. In practice, notice is given at the time the contract is instigated. The process to be followed at the end of the contract is set out in the HR Code of Practice for Reviewing Fixed-Term Contracts.
Staff on fixed-term contracts are protected in law from being treated less favourably than comparable staff on permanent contracts. In addition, staff appointed on successive fixed-term contracts with 4 years or more continuous service are entitled to a permanent contract (unless the fixed-term in their contract can be objectively justified).
The advantages and disadvantages of fixed-term contracts and the potential pit-falls that arise from their use are discussed in the document:
