Budget airline Ryanair has banned its staff from charging their phones at work, saying it is an inappropriate use of office time.
The anonymous Ryanair worker told the Mirror the rule was "petty"
An article in the Daily Mirror claimed staff were "furious" about the rule.
Headed "Power Mad", it quoted a worker saying: "The implication is they are accusing people of stealing electricity by charging a mobile phone."
But a Ryanair spokeswoman said no-one had "batted an eyelid" since the rule was introduced about two months ago.
She said the decision to ban the charging of phones was more related to work ethic than cost-cutting - though "obviously there is a small saving".
"It's not good for people to be charging up their phones in work time," the spokeswoman said.
She said contrary to the anonymous complaints reported in the Daily Mirror, the rule did not appear to have caused any unrest.
"We've had no reaction whatsoever here at head office - nobody has batted an eyelid."
