According to the DfE’s Teacher recruitment website
Holidays
You’ll get more days holiday than people in many other professions. In school, full-time teachers work 195 days per year.
For comparison, you’d work 227 days per year (on average) if you worked full time in an office.

So, it is permissible according to the government, to never be in school when the pupils are not present except for the five compulsory days required. Those days were originally known as ‘Baker Days’ after the Secretary of State that mandated their requirement.
Of course, the DfE site doesn’t say anything about the length of the school day, and the marking and preparation time spent in the evenings, at weekends, and during the alleged holiday period that make up a teacher’s typical working day.
A more useful analyses of the working year might add the following days – assuming the five days pupils are not present account for all the days immediately pre and post the three terms of the year – to the 195 total.
Two hours a day during term-time on marking and preparation and meetings outside a working day of a period between eight am until four pm would add more than a day a week to the total taking it from 195 days (DfE number) by adding an extra 38 days a year meaning the working year would then be 233 days a year compared with the DfE calculation of 227 as an average for an office worker of an unspecified grade. Now, make that an average of three hours a day – probably not unreasonable for most weeks – and the total moves to around 250 days a year.
The length of the working day and the compensation for the length of the working day isn’t something mentioned on the DfE recruitment site. Find a teaching job with no planning – all done for you – and no marking needed outside of the school day – and there are still parents’ evening to attend that can add four days to the total – one half days for each year group plus one for the new intake, plus perhaps a couple of marketing evenings to showcase the school to potential pupils and their parents. Then there are after-school activities ranging from supervising the buses in the car park to accompanying teams to sports fixture, music and drama events and science competitions.
It is difficult to see how a teacher that wants to do their job properly can manage less than 227 days a year.
On top of this, most other workers have been gaining bank holidays over the years, whereas most additional days have fallen within existing school holidays, except for the Bank Holiday at the beginning of May each year. In 2017, the Labour Party suggested the need for four extra bank holidays Bank holidays for teachers? | John Howson (wordpress.com) that suggestion would not have benefitted teachers at all.
So, if told teachers have long holiday, and remember that the DfE says so, remind people that teachers work a form of employer-driven flexitime that means most teachers work longer on average than many other employees, although they do still have job security in most cases and there is the pension to consider.
