I don't know how it works in the private sector but LA paid teachers do not accrue pro-rata holiday pay. If they are permanent teachers, they have 3 possible leaving dates at the end of each term 9with set resignation deadlines) and they receive the pay for the holiday following that term (so 6 weeks if the finish in July but only paid until 31st December if they leave before Xmas. Those on a fixed term contract with an LA school get paid until the date that they leave. If they give the required notice and leave mid-term, they get paid to that date. If they are doing a maternity cover and the permanent teacher 'returns to work' on the first day of the summer holidays, the cover teacher gets no summer hoiday pay and the returning teacher goes back onto full pay.
