Fidelity implies the faithful or loyal performance of a duty and a fidelity guarantee policy is an insurance against the results of dishonesty or disloyalty, both of which stem from a lack of fidelity. Fidelity guarantee may be bought by any organization or person who may suffer as the result of the dishonesty, failure in the loyal performance of duty or, in certain cases, the mistake of another.
The policy covers the employer against loss of money and/or stock through dishonest acts of employees.
