A four-day strike by traffic wardens in Camden, north London was suspended after bosses at private contractor NSL made a new offer.
The strike had been set for Monday of this week.
Members of the Unison union branch voted by almost nine to one to strike for higher pay.
They currently earn £8.92 per hour, less than the London Living Wage.
Workers rejected the offer overwhelmingly. More strike dates are to be announced.
