May Day 2016 celebrates the spirit of workers around the world. Also popularly known as the International Workers' Day or the International Labour Day, 1 May coincides with the first day of spring and is considered as the northern hemisphere spring holiday.

Eighty countries around the world honour workers' rights and the labour movement by declaring a national holiday on 1 May and remember the workers demonstration in Chicago in 1886 for an eight-hour workday rule in which four demonstrators and seven policemen died.

To commemorate the day, IBTimes UK has compiled a top 10 list of powerful quotes that speak about the value and power of hard work and the charm of the arrival of spring.
