The Shortens are remembering the "modest heroes" who will be busy working this Christmas and relying on penalty rates while others relax.
The Labor leader has again filmed his annual Christmas message with wife Chloe, with the pair reflecting on those who will be serving others through the break.
Mr Shorten pays tribute to the troops overseas and their loving families back home who also serve, as well as emergency services personnel.
"We think of all those Australians working this holiday season to make our Christmas run smoothly - modest heroes who get up before the sun rises or work through the night," he says.
"Hard-working people, relying on penalty rates to provide for their families - something I'll always fight for."

Christmas is also a time to spare a thought for those doing it tough - the homeless, those battling loneliness and women and children in refuges, they say.
"We're so lucky that many Australians will roll up their sleeves to provide hot meals, secure accommodation and a little bit of Christmas cheer in hard times."
Ms Shorten urges Australians to be careful on the roads and stay safe around the water.
"We hope all of you have a relaxing break, with the people that you love," her husband says.
"From our family to yours, Merry Christmas."
