For the Mayoral Election in London tomorrow thousands - probably hundreds of thousands - of primary school children will lose a day's education.
Thousands - probably hundreds of thousands - of parents will lose a day's pay, have to take holiday, or be out of pocket paying for childcare.
Thousands of teachers and other school employees will be paid to not do their jobs.
The scale of economic impact must be enormous. Especially on national election days.
Why don't they use community centres, libraries, church halls, a SINGLE hall in a big school (a sports hall with a separate entrance, for example), or if they must use schools have the election on a Saturday!
