I work with children - office with no window

[AsEmptyAsParadise]

NC for this.
I work with children in a support role and for good reason I have been asked to be based in another office. I agreed to this (made perfect sense), except I did not realise it would be a very small office (1.5 metres distance between me and child is possible), but there's no window, so no ventilation is possible. Would this bother you?

The government tells us that children don’t spread it and that school staff are immune.

To be honest I wouldn’t want to be in a windowless room regardless.

No, I absolutely don't want to be in a windowless room either, but specifically in relation to Covid, how would you feel about it?

I'd be concerned.
