2018 State Employer Mandates and How to Prepare Your Business
As you prepare your business for the New Year, it’s important to be aware of legislation that could impact your business come 2018. Navigating local, state and federal laws can be daunting, so our office is committed to providing education and resources about key laws and regulations small businesses might have to comply with. Various laws may have overlapping coverage, such is the case with parental and sick leave laws, so it is important to understand all of the local, state and federal laws involved. In many cases, San Francisco requirements often exceed state laws, although there may be requirements such as employee notifications and other requirements at the state and federal levels to achieve compliance. Governor Brown signed into law a host of new employment laws that affect California workplaces starting January 1, 2018. Here’s a summary of key laws, along with best practices to prepare and ensure compliance. Click here for more details.
