The supermarket's workers have lodged what they're calling a 'life changing' pay claim.
Their union, Mandate, is seeking a 7.7% pay increase, extra leave days, better discounts and more full-time contracts.
It says it believes this is a reasonable request as the rate of inflation is over 9%.
Workers are also demanding fully paid maternity and paternity leave, saying it's 'impossible to survive' without paid time off to care for a newborn.
A survey by Mandate found nine out of ten workers believe more annual leave should be available.
