I am surprised at the figure of 70,000, even if it is an estimate, for fixed-term contract workers of 70,000 to which the Minister of State referred. I thought it was higher and my colleagues in the trade union movement also regard it as too low. I suspect that the use of fixed-term contracts is much more widespread. I am aware, for example, that some local authorities employ staff on a roll-over basis to avoid their legal duties. Sometimes this is not entirely by choice and can be attributed indirectly to the method by which budgets are allocated to local authorities, which means they do not know from one year to the next whether they will be in a position to retain certain workers or groups of workers. They choose, therefore, to employ staff for six-month or one-year periods and renew their contracts as required.
