A former UPS employee filed a complaint with his local Occupation Health and Safety Administration regarding blocked exits at the warehouse where he worked. Soon after reporting hazardous workplace conditions, he was fired from his job. OSHA’s data shows that UPS is cited for blocking exits twice as much as competitors. Additionally, UPS has faced numerous lawsuits due to employees alleging that they have faced retaliation after reporting unsafe conditions.
