Five venues in a popular Melbourne city laneway are accused of underpaying workers.
The hospitality union will stage a protest on Monday, after it found half the venues in Degraves Street are paying employees as little as $11 an hour.
Hospo Voice says the venues have underpaid six workers $50,000 and its findings have been given to the employment watchdog to investigate.
Maggie Stecher-Keyland was underpaid by an estimated $18,619 in wages and superannuation at an iconic Degaves St cafe. Another staff member at the same cafe was deprived of $11,791.
A worker at a cupcake store was said to have lost out on $6900.
"There was zero respect, they made me feel so disposable," Ms Stecher-Keyland said.
"You just get used to it, because the majority of venues in the street are doing the same thing."
Jess Walsh, Victorian Secretary of United Voice, said workers on the street were working eight hours straight without a break or food.
"It's hard to find a tourist brochure that doesn't include a photo of Degraves Street," she said.
"Yet little do the tourists who visit this famous laneway know that it's a meat-grinder that tears through hospitality workers, preying on the youngest and most vulnerable workers."
Hospo Voice has launched a petition calling for venues in the laneway, which is just minutes from Flinders Street Station, to be investigated.
The Fair Work Ombudsman and venues have been contacted for comment.
