Constructive Dismissal is where the employee leaves his or her role as the employer has made it untenable for him or her to continue working.
There is a high threshold for an employee to prove their case. The employee must first have put the employer on notice of his or her dissatisfaction by way of the grievance procedure, in writing. He or she must then await the outcome of any investigation. If the situation remains intolerable, he or she can resign their role and make a claim under Section 2 of the Unfair Dismissals Act. It would be unwise of any employee to resign their role in such circumstances without first taking legal advice.
