The undertaking given by a person to another assuring his integrity is called a fidelity guarantee. A fidelity guarantee is a type of insurance that protects a business from financial losses caused by the fraudulent or dishonest acts of its employees. It assures the employer that the employee will act with integrity and not engage in any dishonest behavior that could harm the company. In simpler terms, if an employee steals from their employer or engages in other fraudulent behavior, the fidelity guarantee will provide financial compensation to the employer to cover the losses. It's like a promise from the employee that they will act honestly and if they don't, the employer has a safety net to protect them from financial harm.
