Recently, the California Employment Development Department (EDD) updated a required California workplace poster — EDD Notice to Employees (DE 1857A). The revised notice is dated May 2018 but was published in July 2018.
The EDD informed the California Chamber of Commerce that, while maintaining updated publications is always encouraged, employers can continue to use the previous version of DE 1857A until January 1, 2019, at which time all employers must post the updated version.
In other words, it is not mandatory to replace this poster until next year.
The EDD recognizes that employers generally replace required notices and pamphlets at the beginning of the year when many changes may go into effect.
