Thank you. Under law you will not actually have the right to be financially compensated at this stage. Any compensation will be at the employer’s own discretion or if it was allowed under contract. The fact that this was not included in your job description would not make a difference unfortunately. If this was not part of your duties then you could have challenged it at the time and informed the employer that you either are not prepared to do it, or if you were going to do it – you would do so if appropriate compensation was agreed. If you had then agreed such compensation it would have become binding and it is what you would have been entitled to. Similarly, if you had agreed to do it at the outset but it soon became clear that it was going to become quite involved and not just a small job you were dong as a favour to the employer, you should have brought that to their attention and tried to negotiate appropriate compensation or advised them that you are not able to continue as it is not a contractual requirement for you to do so.
However, if you had accepted the instruction to do this work and did so without challenging them or agreeing any compensation, it would be implied that you had accepted it as it is. As you are a salaried employee, not a self employed worker, you would have been paid for the time you worked for the company anyway, even if it was not doing the contracted duties expected of you. As such the law would not entitle you to any additional compensation I’m afraid.
You may still try and negotiate that with the employer but if they refuse, legally it would be difficult to take the matter further.
This is your basic legal position. I have more detailed advice for you in terms of the options you have to challenge this internally, 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
