In Vernon v Event Management Catering Ltd EAT/0161/07 the EAT held that a casual worker who, with the exception of a single two-week break to take a holiday, worked every week for more than three years was an employee and had sufficient continuity of service to claim unfair dismissal. He could demonstrate the existence of a contract of employment in each week during the relevant period and the period of holiday did not break his continuity of employment.
