Jetstar ground crew will walk off the job on February 19 for 24 hours after disputes with the budget airline over wages.

According to the Transport Workers Union (TWU), more than 250 staff will strike across the country. The locations include Sydney, Brisbane, Cairns, Adelaide and Melbourne’s Tullamarine and Avalon airports.

TWU National Secretary Michael Kaine said its members were in ‘the fight of their lives for a decent standard of living’.

Jetstar Chief Executive Gareth Evans has hit back at the planned action, labelling it as ‘unforgivable’.

Mr Evans confirmed that the Qantas group offered an offer that included a three per cent pay rise and a year’s back pay, as well as roster benefits.

“The union keeps ignoring the fact that no part of the Jetstar or the Qantas Group will do a wage deal which is more than three per cent,” Mr Evans said.

With flights expected to be delayed and perhaps cancelled, Jetstar has told customers that anyone affected by the strike will be offered a full refund or reschedule.
