Contractors will have to report any labor law violations to federal agencies under an executive order signed by President Obama July 31, 2014.
Contractors will need to disclose any labor law violations from the past three years before a contract can be awarded to them. Violations include family and medical leave, collective bargaining and wages.
The order would also charge agencies with taking contractor labor law violations into account when awarding contracts.
Only contracts valued at more than $500,000 would be affected and the order will be implemented in 2016.
The order also lays out rules for agencies and contractors.
