Construction workers in Melbourne, Australia, protested for the second day in a row on Tuesday in a dispute over mandatory vaccinations.

Nearly 2,000 construction workers protested after the state government in Victoria, Melbourne’s the largest city, mandated vaccinations for workers. The demonstrators have promised to keep protesting, chanting “every day” as they marched.

The union representing construction workers does not support mandatory vaccinations but has distanced itself from the protests.
