The term 'IN A UNION' can be solved by the nine-letter word 'ORGANIZED'. Unions are organizations that represent workers in collective bargaining and other labor negotiations. They are formed to protect the rights of workers and to ensure fair wages and working conditions. Unions are typically organized around a particular industry or profession, and members of the union are usually required to pay dues in order to maintain membership. By joining together in a union, workers are able to have a stronger voice in the workplace and can work together to improve their wages and working conditions.
