An employee is protected from unfair dismissal after two years of continuous service. If the employee started their job prior to 6 April 2012 then only one years’ of continuous service is needed.
An employee who believes they have been unfairly dismissed will need to bring their complaint to the Employment Tribunal within 3 months minus one day from the date of termination of their employment (ie the date they were dismissed). There are some situations where dismissing an employee will be considered automatically unfair.
