Final answer:
Sophia should be worried because she may be blamed for negligent hiring. Employers should conduct thorough background checks and not solely rely on input from former employers.
Step-by-step explanation:
Sophia should be worried because she will likely be blamed for negligent hiring. She had a responsibility to verify the new hire's employment claims and check for any behavioral problems in prior jobs. It is important for employers to conduct thorough background checks and not solely rely on input from former employers. In this case, Sophia should have also conducted a search of the new hire's driving record before hiring him for a job that required driving for deliveries.
