Theatrical unions are organizations that represent professionals in the performing arts, including actors, stagehands, and other crew members. These unions advocate for fair wages, safe working conditions, and benefits such as health insurance and retirement plans. They also negotiate contracts with producers and theater companies to ensure that members receive proper compensation for their work. Some well-known theatrical unions include the Screen Actors Guild (SAG), which represents film and television actors, and the International Alliance of Theatrical Stage Employees (IATSE), which represents technicians and craftspeople. By joining these unions, members gain access to resources, training, and a collective voice in the industry.
