UK firms are being encouraged to clarify rules relating to the use of blogs among employees.
The call follows a survey showing that almost two-fifths of employees had posted details on a blog while at work.
Carried out by YouGov on behalf of workplace group Croner, the survey is highlighting the potential dangers of blogging for employers, with posted information potentially being harmful to a group's reputation.
Gilian Dowling, technical consultant at Croner, said that the situation regarding blogging posed the same problems as those encountered during the advent of email in the 1990s.
She said that "employees were lulled into a false sense of security by the informality that this type of communication brings".
In order to prevent a firm's image from being negatively impacted upon, Croner advises employers to draft a document for staff relating to the issue.
Extending internet cover to incorporate blogging may also be a beneficial move for employers.
A recent survey by networking site Viadeo found that employers are increasingly vetting potential job candidates by searching for information about them on the internet.
