A more thorough explanation:

A jobber's agreement, also known as a Hazantown agreement, is a type of collective bargaining agreement commonly used in the garment industry. It outlines the relationship between a jobber and the contractors who produce the jobber's garments.

The agreement does not cover the jobber's relationship with its own employees. Instead, it governs the relationship between the jobber and the contractors who manufacture the garments that the jobber sells. This includes agreements that the jobber will only use unionized contractors, ensure that salaries and bonuses are appropriately paid, and contribute to employee-benefit funds maintained on behalf of the contractor's employees.

For example, Hazantown, Inc. was a jobber involved in a legal case called Danielson v. Joint Bd. of Coat, Suit & Allied Garment Workers' Union. The Hazantown agreement was used to govern the relationship between Hazantown and the contractors who produced their garments.

Overall, a jobber's agreement is an important tool for ensuring fair labor practices and protecting the rights of workers in the garment industry.
