Thank you for your question.

Nevada is an at-will employment state, which means an employer or employee or may terminate the employment relationship for any non-discriminatory reason (race, disability, age, ethnicity, pregnancy, etc.). This also means an employer may terminate an employer for off duty actions so long it is not based on unlawful retaliatory reason. Therefore, management has significant discretion to regulate the lifestyles and off-duty conduct of its employees, which can include limiting the association of co-workers, even after hours. Since they don't need any reason to terminate you as an at will employee, they can use your doing so to write you up or even terminate you, and it would be considered lawful, unfortunately.
