There are many examples of this practice, not all of which occur in the private sector. In the public sector, for example, there are a significant number of cases of staff being employed for a year or slightly less, for no reason other than the employer's desire to avoid giving them benefits – whether the right to participate in a pension scheme, rights under unfair dismissals legislation or a range of other rights, including the right to take holidays – they would have to give to full-time employees. Our job is to ensure that legal mechanisms of evasion are not used and workers are not deprived of their rights buy virtue of the repeated roll-over of fixed-term contracts, which is currently happening in large measure.
