Final answer:
Tina's comment was unwise because it could be seen as creating an implied contract with the worker, which might hinder the company's ability to terminate employment during a probationary period or later if needed.
Step-by-step explanation:
Tina's statement to the job applicant was unwise because it could be taken as an implied contract that guarantees the worker's employment in the future, potentially making it difficult to dismiss the employee should issues arise. This is problematic because employers often set an official trial or probationary period during which they can terminate an employee for any reason or no reason, sometimes at a lower pay rate, to avoid the risk of hiring an unsuitable worker. Phil advises Tina against making such statements to avoid creating legal implications that could restrict the company's ability to make employment decisions based on job performance.
