Unison officials, representing up to 200 nursery workers in the borough,warned strike action was "even more likely" following the latest talksin a long-running pay dispute.
They want the role of nursery nurse to be upgraded from local authoritylevel three to five, which could mean pay increases of up to 5,000. But they have rejected conditions placed on the shift byGreenwich Council.
Unison branch secretary Onay Kasab revealed the offer could meanincreasing the standard working week from 32.5 to 35 hours, being paidfor term-time only and losing an entitlement to free school meals.
This effectively wiped out any benefits of regrading, he said.
Greenwich council said strike action was not in the best interests ofthe nursery nurses or the children. "We are determined to continue withthis process and find a solution that is acceptable to both parties bythe start of April," said a spokesman.
