A CPA firm wants to gain a competitive recruiting advantage over its peers. Its lead recruiter has started giving $2,000 signing bonuses to brilliant 18-year-old high school graduates who plan to major in accounting during their upcoming college years. In return for these bonuses, students must agree that, if they decide to join the accounting profession upon graduation, they must accept employment with this CPA firm. This CPA is highly reputable and social media sites confirm that it pays its employees "top dollar." If bonus recipients attend information sessions for other CPA firms or interviews with other firms while in college, their offer of guaranteed employment with this firm terminates. Is this CPA firm's policy legal? Or ethical?
