An employee who is suspended pending an enquiry means that the employee has committed some wrongdoing against a person, system, or otherwise. By resigning, that employee wants to avoid punishment for their wrongdoing. In the case of resignation, the complainant has a veto. Only if the complainant agrees can the suspended person resign.
If the employer accepts the resignation without consulting the complainant, the employer is wronging the complainants. This action could strain relations with existing employees at the cost of the suspended and resigned employee, who will no longer have any involvement with the organization, employer, or employees.
Even when the suspended employee submits a resignation, it is up to the employer to accept or reject the resignation. The employer is not bound to accept the resignation because they have the option to terminate the employee. This termination can serve as an example for existing employees, demonstrating the consequences of misbehavior.
