A loophole in the national insurance rules means that the council, jointly controlled by Labour and Liberal Democrats, will be able to release hundreds of thousands of pounds for services, reports The Times (p6).
Under current rules NI contributions are calculated on the amount of cash paid to staff, so the authority can slash its bills by paying them in kind.
Councillors hope to pass the schme in time for the next financial year because the loophole will be closed in April.
'For example, if 25% of the council's 15,500 staff received 10 per cent of their pay in vouchers, the saving would be£500,000 in the coming financial year,' he said.
If the scheme is approved, staff will be asked whether they would mind receiving some of their pay in their choice of supermarket vouchers.
