Andre and Chip work as forklift operators in a warehouse. They work with about $100$ other people who have various warehouse jobs. They have been concerned about the safety of their work environment because their employer never services the forklifts when maintenance should be done. One of the workers has already been injured because the one of the forklifts had a brake malfunction. Andre and Chip organized a meeting of all the workers do discuss whether the workers want to form a labor union to negotiate for safer conditions and better pay. As soon as the employer learns about the meeting, Andre and Chip are fired. Please discuss any legal issues in this situation.
