Thank you. Whilst there is nothing stopping them from asking your employer for your information, they should not disclose that because it would amount to a breach of data protection. So the employer should keep such data confidential.
In terms of defamation, certain conditions must be met for the statement to be classified as defamatory. These are:
1. The statement has to be untrue.
2. It must directly identify the complainant.
3. It must have been published, usually communicated to at least another person.
4. It must be in a form of words, which would tend to lower the claimant in the estimation of ‘right thinking members of society generally', expose the claimant to hatred, contempt or ridicule, or cause the claimant to be shunned or avoided.
5. Its publication has caused or is likely to cause serious harm to the reputation of the claimant.
Whilst it may be easy to prove that defamation has occurred, the legal process of pursuing such a claim is extremely complex and expensive. As this goes through the High Court, you would need the professional help of specialist defamation solicitors and the costs are undoubtedly going to run into the thousands right at the outset. Also there is no legal aid available for such claims so the complainant must fund these personally. So when you hear about defamation claims being made, these are usually pursued by big corporations or celebrities who have a public image to protect.
You must also consider whether you can defend the claim. Even if they satisfy the criteria to prove the statement was defamatory it could be defended on a number of grounds, including by providing evidence that the statement was substantially true or an honest opinion. You have evidence to back up what you wrote and even if they do not like it and it has affected their business, if it was true, there would be no defamation.
So do not overly worry about this – I think they are probably annoyed (understandably so) but do not get too concerned with what they can do or are threatening to do because realistically that will unlikely happen.
