California supervisors carry obligations that line employees do not, and the training reflects that. Two hours every two years, covering not just what harassment is but what a supervisor is required to do when they learn about it.
The supervisor mandate is the older half of California law. AB 1825 created it in 2005 for employers with fifty or more employees. AB 2053 added abusive conduct and workplace bullying in 2015. SB 396 added gender identity, gender expression, and sexual orientation in 2018. SB 1343 then lowered the threshold to five employees and brought non-supervisory staff into scope. All of it now lives in Government Code section 12950.1.
Who counts as a supervisor
California defines this by authority rather than job title. Anyone with authority to hire, transfer, suspend, lay off, recall, promote, discharge, assign, reward, or discipline other employees is a supervisor, as is anyone who directs other employees or handles their grievances, where exercising that authority requires independent judgment.
In hospitality and retail that reaches further than people expect. A shift lead who schedules, a floor manager who disciplines, and an assistant manager who handles complaints are all supervisors under this definition, whatever the title on the schedule says.
Deadlines
Two hours of effective interactive training, every two years
New supervisors within six months of assuming supervisory duties, whether hired in or promoted
Promotion restarts the clock, so an employee trained as a line worker in January still needs supervisor training within six months of being promoted
Local agency officials have their own version under AB 1661: training within six months of taking office, then every two years.
What supervisor training adds
Beyond the employee content, supervisor training covers the obligation to report harassment they observe or learn about, how to respond to a complaint without retaliating, the limits of promising confidentiality, documentation, and the supervisor personal exposure that comes with the role. It also covers abusive conduct and bullying under AB 2053, which is not itself unlawful but must be addressed in the training.
California context
Sacramento is the capital, with the workforce concentrated in Los Angeles, San Diego, San Jose, San Francisco, and Fresno. In a state with this much hospitality, tasting-room, and wine industry employment, supervisory turnover is high and promotions happen fast. The six-month promotion window is the one most often missed.
Keeping supervisors current
Promotion is the trigger that breaks most tracking systems, because it does not look like a hiring event. A company account lets you assign the supervisor course the moment someone changes role, track two-year cycles per person, and hold the completion record that demonstrates you met the deadline.
