Polygraph screening of domestic staff

When you hire a nanny, housekeeper, driver, or caregiver, you are entrusting them with what is most precious to you—the safety of your loved ones and the security of your property. Unfortunately, references and resumes do not always reflect a person’s true history. A polygraph test is the most effective way to verify the trustworthiness of staff and prevent potential risks as early as the hiring stage.
