At work (NHS Hospital) we make teas & coffees for our breaktimes.
Now, we were originally allowed to use the same milk that we use for the patients, the same tea bags and coffee, and the same sugar.
Suddenly Management decided that it was 'wasting money' and staff have to bring in their own milk, tea, coffee & sugar from home. To use the hospital's items would be a disciplinary offence.
Soon the ward fridge was overflowing with about 30 people's different milks, and the ward office was packed with tea bags and coffees.
The Clinical Leader (Sister) got so fed up with the mess that she said we could all use the hospital's milk and tea etc again and not to bring in milk from home.
So we've all gone back to using the hospital's teabags, coffee, milk & sugar sachets.
Technically we could all get disciplinary warnings for using the hospital's stuff... but none of us care that much because we work bloody hard and don't get any thanks for it.
So there is an example of being able to be punished for using the workplace's sugar sachets!
