Discuss briefly if each termination is valid and why or why not:
a. Larry is concerned about the working conditions at his job site and contacts OSHA. His supervisor overhears him making the call and fires him for his lack of loyalty.
b. Sarah is told on the day she is hired that she'll always have a job here as long as she shows up on time and works hard. The employee manual reinforces this and provides that she can only be fired for cause. One day she is called into the office and dismissed without an explanation and she believes she did all the company asked.
c. Mark walks into work one day wearing a Cowboys shirt and his boss, an Eagles fan, fires him.
