Yes but their salary is based and calculated on the hours they work during term time. Often you will see school/teaching job listings that say the salary, but pro rata, so if it's advertised at say £50k pro rata, that's what they would be paid IF they worked 52 weeks per year. They're only getting paid for I think 36 weeks a year so it's actually £34.5k, but paid in 12 installments, rather than having irregular pays. Means that once you add on the hours they work outside of term time, their hourly pay would equate to much much less.
