Key Post: Hygiene/Vermin in Workplace



My husband's factory is swarming with mice, leaving their mark in the canteen, on the worktops, even in the toaster (ugh...). Plus, the toilets were never kept in tip-top condition. And there's a need for provision of lockers to keep workclothes/belongings....
Unfortunately, there's no union representation, and the workers didn't bother to get around to that ...
What sort of action should be done to get the employer accept his responsibility - 'duty of care' - for the health and wellbeing of his staff? Contact the Dept of the Environment to send over a health inspector? Any ideas?
Thanks in advance,
