Just to add to my previous comment -
Frankly, no man should be a nursery worker, imo. It introduces an unnecessarily heightened degree of risk and has no net benefit. Better to tighten safeguarding, improve training, raise pay, and stick with the comparatively much lower risk that women present.
But this man may as well have been a walking red flag. Even if a nursery was forced to hire men, why on earth would they choose that one?!
