Collecting evidence
As soon as you become aware of a negative comment that has been posted on a social networking site by an employee, you should begin collecting evidence that may be referred to in any disciplinary proceedings.
The evidence may include screenshots or printouts of the offending material and records of any complaints received from customers, any evidence of damage caused by the posting, and in the case of a claimant that trades for profit, any financial loss suffered, or likely to be suffered as a consequence.
The extent of publication should also be investigated, for example, whether there is unlimited access to the content or access is restricted, or how many “followers” or “friends” the employee has on the relevant social networking site.
When collecting evidence on an employee’s social media use, you must ensure that you do not disregard the employee’s privacy rights.
