Washington State Attorney General, Bob Ferguson, announces his 2019 legislative agenda, which includes a bill that enables the state to penalize employers for not paying their workers the prevailing wage, even if the wages have been paid back to the employees before the State has taken action. If the bill passes, it will take effect on January 1, 2020.
