John is a very diligent worker committed in carrying out his duties. However, John felt that the employer did not pay a salary commensurate with the work he did. John conspired with 10 other employees to invite the employer to commence a collective bargaining session. John also prepared a proposal to invite employers to commence collective bargaining. The proposal was sent to the employer on 2 March 2022. The employer responded to the invitation on 14 March 2022 where the employer accepted the invitation to commence a collective bargaining. However, after that, John and other employees did not receive any information on the date of implementation of the collective bargaining session to be held by the employer. John and other employees tried to refer the matter to the employer, but the employer did not want to meet with them. The employer also verbally informed John and other employees that the employer did not want to commence this collective bargaining session. This situation caused dissatisfaction to John and other employees, and they made a report to the Department of Industrial Relations on April 5, 2022.
