OK, so first of all you may not be able to take these last couple of days as holiday if you have not given sufficient notice to do so. Under law the notice you must give is at least twice as long as the requested days, so in your case you need to have given them 4 days’ notice. Even if you did, they can reject your request by giving you notice equal to the requested days, so they can give you 2 days notice of their refusal. However, if they have refused your request you are still legally entitled to be paid for these days.
In terms of having to go back in, you do not have to and no one can force you to. There are circumstances when an employee may be entitled to leave with immediate effect and without honouring their notice period. This occurs when an employer has committed a serious breach of contract first. The whole contract, including the notice periods, then becomes immediately void and the employee would be treated as being 'constructively dismissed'. So if there are reasons to believe the employer has acted in breach of contract, whether a breach of an express contractual term, or other breaches such as bullying, exposing the employee to unreasonable stress, discriminating against them, etc. this reason can be relied on in order to leave with immediate effect.
In terms of suing for defamation or similar, whilst this may appear to be a potential case of defamation (this includes libel if it is in written form, or slander if it is in oral form), such claims are rather difficult to pursue. Many people are keen on suing for defamation without having full appreciation of the law or practicalities in doing so. I will try and clarify the position below.
First of all, certain conditions must be met for the statement to be classified as defamatory. These are:
1. There has to be a defamatory statement - the assessment that is often used to establish this is whether the statement tends to lower the claimant in the estimation of right-thinking members of society generally
2. Its publication has caused or is likely to cause serious harm to the reputation of the claimant – this will vary based on what effect it will have but it really has to be something sufficiently serious
3. The statement has been published by the defendant to a third party
4. The claimant must prove that the words complained of were published about him - this should not be an issue if the claimant is named or clearly identified.
Whilst it may be easy to prove that defamation has taken place, the legal process of pursuing such a claim is often complex and prohibitively expensive. A claim must be made in the High Court and will likely require the help of professional defamation lawyers, so the costs will often be high right from the outset, usually in the thousands. There is also no legal aid available for such claims so the complainant must fund these personally.
You must also consider whether the publisher of the statement can potentially defend the claim. For example this can happen by proving the statement was true or an honest opinion which could have been made based on the available facts.
Instead of starting legal proceedings it would be best to contact the publisher of the comment, advise them that what they have done amounts to defamation and that you will consider pursuing the matter further if they do not retract their statement and issue an apology. This could prompt them to reconsider their position, which would avoid the need for court action. Of course, if they refuse to comply the option of suing still exists, but consider the above information before going down that route.
