Iran's manual workers demand better rights and benefits
Iran's labour union has been pressing for several years for the country's labour law to be re-written.
In its current form, the law allows employers to fire workers on the spot, so long as they notify them in writing and pay a month's salary for each year worked.
And according to the union, 40% of the country's manual workers are hired without contracts and paid by the day.
