The NHS Greater Glasgow and Clyde employee is facing disciplinary action for tweets posted from his account that breach the board's social media policy.

One post says: "They've tried it a few times mate. I just go straight to my doctor and get a fortnight line for stress and sit in the house on full pay and enhancements. They will learn soon enough."

It says: "Some employees believe they should be able to say what they want on their own social media sites, especially if these comments are made outside of work.

"Employees sometimes use social networking sites, emails or other forms of social media to air their grievances.

"Social networking can be an excuse for avoiding face-to-face conversations. Many of the issues that lead to disciplinary and grievance problems at work can often be dealt with by a manager having a quiet word with an employee - which can prove hard if line managers have become reliant on communicating electronically.

"The best approach is for an employer to make it clear to employees what online conduct is acceptable, and what is not, and deal with any issues through the same procedures it would deal with any other kind of disciplinary or grievance matters."
