Collective Association

A collective agreement, collective labour agreement (CLA) or collective bargaining agreement (CBA) is a written contract negotiated through collective bargaining for employees by one or more trade unions with the management of a company (or with an employers' association) that regulates the terms and conditions of employees at work. This includes regulating the wages, benefits, and duties of the employees and the duties and responsibilities of the employer or employers and often includes rules for a dispute resolution process. via Wikipedia ↗
