It is a global event, as people get out in the streets in the thousands protesting against austerity cuts, living costs, government policies and low salaries. On the list too are unemployment and rising consumer prices worldwide.
In Asia, protests were organised by left-wing parties and trade unions. The demonstrations are for higher pay and better working conditions and protesting government policy, as the cost of living spikes all over the continent.
May Day sees protesters in the Phillipines, Taiwan, Malaysia and Indonesia, demanding pay increases as they cannot survive with the rising consumer prices in the countries. They are also requesting lower school fees. In the Phillipines, one worker states that she earns only $70 a month and that it is almost impossible to survive on such a small salary.
Workers in Indonesia
have formed Asia's largest demonstration and there is a heavy army and police presence on the streets. Protesters are carrying banners saying "stop outsourcing contracts" and "raise our salaries". The demonstration started with around 9,000 workers who gathered at Jakarta's main roundabout before marching to the state palace.
Police spokesman in Jakarta, Rikwanto stated that around 16,000 policemen and soldiers had been deployed to guard the protest.
A protest leader, Muhamad Rusdi told AFP
that, "Living costs have gone up but our salaries remain unchanged."
"We only make enough to eat but there is no money in the bank, no money for our children's education."
The Philippine capital
, Manila, sees around 8,000 members of a labor alliance, many wearing red shirts and waving red streamers, who marched towards the presidential palace.
However, Philippine President Benigno Aquino III has rejected their calls for a pay hike. He warned that this would only worsen inflation, spark layoffs and turn away foreign investors.

Protests are happening all over Spain
, especially with the huge increase in the number of unemployed which has risen to just under 25%. Tens of thousands have massed in central Madrid's Neptuno square, protesting the new labor reforms which make it easier to fire workers and also the austerity budget cuts in relation to both education and health care in the country.
