A more thorough explanation:

Area bargaining is a process where a union negotiates a collective-bargaining agreement with multiple employers in a specific geographic area. This means that the union represents the workers of different companies in the same area and negotiates with all of them at once.

For example, a union representing hotel workers in a city may negotiate with all the hotels in that city for better wages, benefits, and working conditions. Another example could be a union representing construction workers in a county negotiating with all the construction companies in that county for better pay and safety measures.

Area bargaining allows unions to have more bargaining power by representing a larger group of workers and negotiating with multiple employers at once. This can lead to better outcomes for workers in terms of wages, benefits, and working conditions.
