Deliveroo riders in Dublin went on strike for two hours last night in a protest over pay and conditions.
They are seeking increased delivery fees for taking meals to customers and measures to improve their safety while working.
They said on social media that they hoped their action would ensure people "realise the importance" of their work.
It is not known how many took part in the action.
Korean restaurant Chimac switched off Deliveroo during the strike hours from 6pm to 8pm as a "demonstration of our solidarity".
"These men and women have got us, and you, through the last 10 months of madness - they work incredibly hard," it said on Twitter.
In a statement, a Deliveroo spokesperson said: "The safety of riders is our absolute priority and we take every step to ensure they feel safe when on the road.
"We were the first delivery platform to give all riders free insurance to protect them in case something goes wrong while on the road, and we are constantly looking at new ways to extend our support.
"We plan to introduce free personal safety alarms for all riders in Ireland that they can use in an emergency.
"We also work very closely with the police and authorities to help protect riders and resolve any security issues they face."
In relation to pay, the company has said that following feedback from riders, it introduced distance-based fees, a structure that pays riders more for medium and long-distance deliveries.
Labour senator Marie Sherlock said her party stands with Deliveroo riders, adding that the workers are asking for engagement on very basic issues.
Fine Gael senator Mary Seery-Kearney also shared her support, saying: "They are a lifeline during lockdown."
