Rob Jensen worked for 8 years as a messenger for High Tech Advertising Agency, a company without a unionized workforce. On his 8thanniversary with the company, Rob was called in to the president's office, was given a 10 percent raise, and was complimented on his diligence. The following week, a new head of the messenger department was hired. He wanted to appoint his nephew to a messenger job but discovered that a company-wide hiring freeze prevented him from adding another employee to the messenger ranks. So he fired Rob and hired his nephew. What remedy, if any, does Rob have? What additional facts might change the result?

Can you give a lots of explanation, thank you.
