NHS Trust officials in Manchester have excluded the stationary because many members of their staff have cut their fingers while using them.
An email was sent out to workers that stated: "Due to recent incidents, NHS Manchester has decided to immediately withdraw the use of metal paper fasteners.
"Please ensure any that remain in use be replaced by similar plastic fasteners. The use of metal fasteners is prohibited and must be carefully disposed of immediately. Thank you for your cooperation."
Some of the staff have branded the new rule as nannying. One worker said: "It is ridiculous. They're vaguely sharp, like drawing pins and fountain pens.
"I can only assume that the top brass think that they've employed idiots who need nannying through the working day."
A spokesman for NHS Manchester said the rule had been created after one member of staff cut their finger but took it no further.
This rule comes in a long line of others put into place for Health and Safety reasons in Manchester workplaces.
