Non-union is a term used to describe a situation where employees or workers are not affiliated with a trade union. There are several synonyms for the word non-union, including unorganized, independent, non-affiliated, and unrepresented. These terms are often used interchangeably with non-union to describe employees who are not under any collective bargaining agreement or union representation. While non-union workers often enjoy more flexibility in their work arrangements, they may also be more vulnerable to workplace abuses and violations. As such, it is important to advocate for the rights of both union and non-union workers to ensure fair working conditions for all employees.
