A couple have resigned from their jobs at an Aberdeen-based oil company after an intimate email exchange was accidentally forwarded to all staff.

Integrated Subsea Services receptionist Melanie Anderson had been emailing fiancé Eric Knisz when she sent a short note to colleagues to inform them that the sandwich van had arrived, The Daily Telegraph reports.

However, the messages she had previously exchanged with Knisz, which made reference to their sex life, were also forwarded to the office.

The email chain quickly went viral, leading to a series of jokes posted on Twitter with the hashtag #sandwichvan.

Integrated Subsea Services human resources director Bruce Webster referred to the incident as a "silly mistake" and said the pair were "absolutely mortified".

"While the couple involved made a silly mistake, they did not do anything malicious or unlawful and have therefore not been disciplined. Regrettably they have chosen to resign," he explained.

Webster added: "We are however dealing seriously with the issue of the email going outwith our organisation and reinforcing our policies in relation to this."

Awkward.
