Do i have a case at work?

Maybe. But not for the reasons you mentioned. If a colleague / co-worker discriminates against you or causes you to suffer adverse terms, conditions of employment then you may have a claim against both the employee and your employer. Think Title VII, because of race, religion, national origin, color, sex, gender, marital status, sexual orientation, disability, age, and more. A hostile workplace, more than petty slights or trivial inconveniences, may be actionable across New York State. But you will likely want to work with an employment lawyer and may have to gather evidence to support such a claim. We rarely if ever suggest that anyone resign. Quitting is a last resort and almost never suggested. Work with an employment lawyer. Some of us work with clients or potential clients for a couple years to gather evidence and try to help the employee stay on the job while gathering evidence. Employees who hang in there, record information, and truly endure hostile, sometimes abusive workplaces, can recover respectable damages. Call some employment lawyers before you take it on yourself. Never easy claims.
