Two nurses from Mid Staffordshire Foundation Trust posted photos of themselves on Facebook having a food fight in a clinical area around a month after the trust received scathing criticism over standards from the Healthcare Commission.
Pictures of the incident, thought to have taken place last May, were posted on Facebook in December but removed soon after, when the trust found out.
Trust chief executive Antony Sumara said: “We will not tolerate unprofessional behaviour by any of our staff.
“As soon as we were made aware of the photos in December 2009 we launched an investigation and appropriate action was taken.
“The Facebook content was removed immediately and we issued a reminder to all our staff about the appropriate use of social networking sites.”
