More than a third of blogging employees are posting information about their employer, workplace or colleagues on personal blog sites, according to a survey by workplace experts Croner.

The survey found that 39% of those keeping blogs admitted that they had posted details, which could be potentially sensitive or damaging about their place of work, employer or a colleague.

Gillian Dowling, technical consultant at Croner, says: “An employee can be lulled into a false sense of security and sound off about his bad day at work on a blog without fully considering the impact such a posting may have.

“If there is a negative impact on the organisation’s corporate image which is so serious that it breaches the implied term of mutual trust and confidence, the employee could be dismissed for gross misconduct.”

She adds that confidential secrets could be disclosed including financial information or new product development. She advises that employers should carefully consider the impact of blogging on their organisation and take appropriate steps to minimise any potential risk.
