How can the government condemn the teachers' strike and then use schools as polling stations?

Many people, not just the government, condemned teachers for wasting a day of education. However, every seems fine with many schools in the UK being closed tomorrow to be used for voting. Surely there are plenty of church halls and community centres that would be available. Seems like a big old double standard to me. Does anyone know why schools are used?

Thats the government for you...

Schools are paid for by voters, not only teachers (I completely acknowledge they pay taxes). The double standard would be if taxpayers could not use facilities they paid for to vote. .

it happens only in india
