Brazil’s Labor Ministry says labor laws have been broken and health and safety standards not met in construction of the Olympic Park and athletes village for the 2016 Olympics in Rio de Janeiro.
The ministry announced the irregularities on its website.
It says workers have been made to work beyond the two-hour overtime limit, have not been given 11 consecutive hours of rest between shifts, and not received the mandatory one day off a week.
Inspectors found workers were not obliged to use personal protective equipment like gloves, safety glasses, shoes, earplugs, and hard hats.
Safety flaws were also found in temporary electrical installations.
