Workers and union leaders around the world have dusted off bullhorns and flags that had stayed furled during coronavirus lockdowns for slimmed down but still boisterous May Day marches.
They are demanding more labour protections amid a pandemic that has turned economies and workplaces upside down.
In countries that mark May 1 as International Labor Day, the annual celebration of workers' rights produced a rare sight during the pandemic; large and closely packed crowds, with marchers striding shoulder-to-shoulder with clenched fists behind banners.
But in Turkey and the Philippines, police prevented the May Day protests, enforcing virus lockdowns.
For labour leaders, the day was a test of their ability to mobilise workers in the face of the profound economic disruptions.
In France, thousands took to the streets with trade union banners and flags.
The face masks worn by many were a reminder of how much life has changed since the last traditional May Day celebrations - in 2019, before the spreading coronavirus wrecked lives and livelihoods and eroded civil liberties, often including the right to demonstrate.
Some marches, constricted by coronavirus restrictions, were less well-attended than was traditional before the pandemic. But they still served as outlets for workers' concerns over jobs and protections.
In Indonesia, Southeast Asia's largest economy, thousands vented their anger at a new job creation law that critics fear will reduce severance pay, lessen restrictions for foreign workers, increase outsourcing and hurt workers in other ways as the nation seeks to attract more investment.
Protesters laid tomb effigies on the street to symbolise hopelessness.
In the Philippine capital of Manila, where a month-long coronavirus lockdown has been extended by two weeks amid a surge in infections, police prevented hundreds of workers from demonstrating at a public plaza, protest leader Renato Reyes said.
But protesters did gather briefly at a busy Manila boulevard, demanding pandemic cash aid, wage subsidies and COVID-19 vaccines amid rising unemployment and hunger.
"Workers were largely left to fend for themselves while being locked down," labour leader Josua Mata said.
In Turkey, a few labour leaders were allowed to lay wreaths in Istanbul's Taksim Square but riot police stopped many others from reaching the plaza.
The Progressive Lawyers' Association said more than 200 people were detained.
Turks are barred from leaving home, except to collect essential food and medicine, under a lockdown until May 17 that aims to halt a surge in infections. Protests were also banned around Taksim Square.
In France, political leaders on the far right and the far left who are expected to be President Emmanuel Macron's main challengers if he stands for re-election next year tore into his policies and his handling of the pandemic.
France has seen over 104,000 COVID-19 deaths since the pandemic began.
