Many thanks for your patience. So there are two issues here – one is the retraction of the offer and the other is the potential negative feedback, which could impact you for the future.
As far as the retraction of the offer is concerned, this is likely to amount to a breach of contract because you had a formal offer, which you accepted and in turn this would have created a legally binding agreement. So a contract would have been in place. If the offer was not conditional on anything and they then retracted it, then that would amount to a breach of contract. Usually you would be seeking compensation to the value of the notice period you would have been entitled had you been terminated once in the job. That is because if you think about it, they could have fulfilled the contract by allowing you to start and then issued you with notice of termination on day one of your job and they would have acted completely legally. So you are basically prevented from receiving the notice period you were entitled to had you been allowed to start working there.
In terms of being slandered, that can be difficult to deal with. If this was done as a result of a written reference, where you could refer to the slanderous comments, then that could be pursued. However, if this was done verbally and neither party wishes to reveal what was said, it would make it impossible to take it further because you have no idea what was said and if what was said was untrue. It is an unfortunate reality but people do get ‘blacklisted’ from certain jobs simply through word of mouth or private discussions between those who make the decisions. These cannot really be challenged as no one can prove what was said or that anything was said so you just have to hope that it does not affect other potential prospects in the industry (I am sure they would not know everyone in the industry or speak to them).
This is your basic legal position. I have more detailed advice for you in terms of the steps you need to follow should you decide to take this further for compensation, which I wish to discuss so please take a second to leave a positive rating for the service so far (by selecting 3, 4 or 5 stars) and I can continue with that and answer any further questions you may have. Don’t worry, there is no extra cost and leaving a rating will not close the question and we can continue this discussion. Thank you
