The Fair Work Commission will deliver a long-awaited decision on the future of weekend penalty rates today, reigniting a political fight between Labor and the Coalition.
The commission has been hearing evidence from industry groups and unions since 2015, but repeatedly delayed a decision until after the federal election last year.
It will decide whether Sunday penalty rates should be brought in line with Saturday penalty rates, with employers and some Coalition MPs arguing they are no longer appropriate.
The decision would apply to those working in retail, hospitality or fast-food industries.
