Protesters in the Philippines burned a sculpture of President Rodrigo Duterte during a May Day rally outside the presidential palace in Manila.
Trade unions are angry that companies can still hand out short-term contracts that don't provide stable benefits to workers. Duterte promised to do away with the practice on the campaign trail in 2016.
In Berlin, the crowd was largely pro-union and anti-capitalism.
"We have more rich and even richer people than we ever had before," protester Aimo Tuegel told the Associated Press. "On the other hand, work and working conditions for workers are continuing to get worse."
In Paris, union marchers took to the streets to protest President Emmanuel Macron's months-old economic reforms, which are aimed at making it easier for companies to hire and fire employees. But they weren't alone.
Hooded and masked anarchists were in the Parisian streets too, smashing windows, throwing cobblestones, and lighting cars on fire.
More than 200 protesters were arrested and at least four people, including one police officer, were injured in the violence, Reuters reported.
In Istanbul, some protesters shouted "long live May 1."
Dozens of people were detained in the Turkish city after trying to enter a square the police deemed off-limits to protests, according to the Associated Press.

Neo-Nazis and far-right leaning groups in Germany have also started using the day to stage demonstrations of their own.
Violent clashes between left and right-wing protesters have been breaking out on May 1 in cities like Hamburg and Berlin for decades, according to Deutsche Welle.
And in Poland, this supporter of the far-right National-Radical Camp (ONR) raised his hand in Warsaw.
In Switzerland, the day was marked by more playful protests, as clowns wiped down a Swiss police car in Zurich.
But in Taipei, Taiwan no one was laughing as workers took to the streets to protest their long hours.
Russians also celebrated their own Labor Day in Moscow, but some who were there to raise awareness for mental health issues were violently arrested, according to the English-language weekly paper, The Moscow Times.
