Pilgrim's Pride review: Retaliation

I am a co worker that feels James Johnson has been retaliated on and discriminated against because of a complaint that was filed. He works different shifts to help and accommodate other employees in need of training without any additional pay. This is not included in his job description but he complies to be a team member. He is not made aware of of being scheduled for 3rd shift until receiving a call on Sunday as to why he is not at work. He receives a point for being late which was not his fault for to miscommunication from him manager not informing him of the schedule. He is then told by his manager not to call or text him anymore. What is said in confidence is being relayed to others and taking out of context and causing animosity between employees to seem as though James is being difficult to work with.
