The head of under-fire power company Ascendant said yesterday controversy over redundant staff was “the most mentally draining” experience of his professional career.

Sean Durfy was speaking after three marketing staff lost their jobs at the parent company of electricity company Belco last week. Their roles were outsourced to design and marketing firm Cosmic.

Mr Durfy wrote a letter to staff just before 1am yesterday morning that said: “I can’t sleep.”

He added: “I have read stories, quotes, innuendo, conspiracy theories and outright lies in all forms of media.

“I have lived both my personal and professional life as an open book, sharing all parts of me and my thoughts — both the good and the bad — with whomever asked.

“I have made and will make decisions about how we run this company to the best of my ability.

“Some of those decisions will be very difficult. I will always make sure that I have the interest of all stakeholders in mind — and that is our customers, our employees, and our shareholders.”

Mr Durfy said his staff were “the most important stakeholder I report to” and told them he would be available to speak to any employee who wanted to share concerns or ask questions.

He added: “I know you may have questions and concerns about what has been reported in the media.

“You may also have questions about the company’s future given what you are hearing from all other sources.”
