Is workers compensation mandatory for New York city based small businesses?

Not only is it mandatory it could save your business. If an employee is injured while providing services for you don't you want workers compensation to be their exclusive remedy? If you don't have it their medical bills could exceed your income for the rest of your life. Here's a link from the Department of Labor with civil servants who I believe will gladly assist you with unemployment insurance, paid sick leave, short term disability, workers compensation, premises liability, commercial coverage, cybersecurity, errors and omissions, and much more. https://dol.ny.gov/location/new-york-city-business-services-regional-office
