Yes, as of February 8, 2020, ALL New York employers are now covered by the NY State Human Rights Law (NYSHRL) regardless of employer size. Even if you're the only employee in the company, you are protected by the NYSHRL if you feel that you're being discriminated against for a protected status and working in a hostile work environment.

The link to the NY State Division of Human Rights' complaint form and instructions for filing is below. This is the state administrative agency that enforces employment discrimination claims under the state's Human Rights Law, but if you worked in NYC, there's also the NYC Commission on Human Rights, the city administrative agency that enforces the city's Human Rights Law, and the US Equal Employment Opportunity Commission that handles all employment discrimination complaints under federal law. It's best to consult with a qualified employment lawyer before committing to filing a complaint in one particular agency, as where you file and when can affect your future legal leverage and options. https://dhr.ny.gov/sites/default/files/pdf/nysdhr-employment-complaint-form.pdf

Yes, independent contractors are now covered and protected by the NY State and the NY City Human Rights Laws that cover workplace discrimination, although federal anti-discrimination laws still only apply to traditional "W-2" employees.
