Despite recent strikes and protests by staff and the ensuing negative publicity that came with it Dunnes Stores has increased its market share by a greater margin than its two main rivals.

Between early March and late May the value of Dunnes Stores grocery sales grew by four percent when compared to the same period last year. In contrast, Supervalu experienced a 1.2 percent increase while Tesco’s turnover went down by three percent over the same period, according to Kantar Worldpanel Ireland.

The figures show that it was the sixth straight month of growth for Dunnes. The average spend per shop rose in the supermarket while the average amount of items purchased per customer also increased.

The news of Dunnes continued success comes after a weekend rally in Dublin by disgruntled staff.

About 3,000 people took to the streets in the capital on Saturday to voice their anger at working conditions at Dunnes. The Mandate trade union said that staff “do not know what hours they’ll have on a week-to-week basis and consequently their income can fluctuate from approximately €144 per week to €400 per week.”

Gerry Light, Mandate assistant general secretary said: “It is totally unacceptable that a local manager in Dunnes Stores can pick and choose which individual members of staff will be able to provide for their families at the end of a week.

“There are many Dunnes workers who have been with the company for up to 10 years doing 35 hours per week, only to have their hours slashed overnight and the company then hires new staff on lower wages. This is a complete abuse of power and it must be stopped.”

Last month Dunnes did approve a 3 percent pay increase for staff.
