Interactive Data Corp. hired Foley as an assistant product manager, and over the next six years, Interactive steadily promoted him. Interactive officers repeatedly told Foley that he would have his job as long as his performance was adequate. They also distributed an employee handbook that specified termination guidelines that included a mandatory seven$-$step pre$-$termination procedure. Foley learned that his supervisor was under investigation by the FBI, and he told Interactive officers. Shortly thereafter, Interactive fired Foley. He sued, claiming that Interactive could fire him only for good cause after the seven$-$step procedure. Who wins?

a$.$ Interactive wins because the seven steps were only an implied, not express, condition to its employment contract with Foley.

b$.$ Foley wins because he and Interactive had a bilateral, express employment contract that incorporated the seven steps.

c$.$ Interactive loses because it had an implied employment contract with Foley that incorporated the seven steps.

d$.$ Foley loses because he and Interactive had a unilateral, express employment contract that incorporated the seven steps.
