Many thanks for your patience. A caution by itself will not automatically put your job in jeopardy. It is not a criminal conviction, it is one of the least serious ways to dispose of criminal issues. How it may impact your job depends on the nature of your job and the offence for which you were cautioned, together with the circumstances leading up to it.
What the FCA registered employer would be looking for is whether this is a serious offence which affects your ability to do your job and makes you unsuitable to hold such a position. Assault in general is not considered that serious, unless it was a listed offence such as assault against minors, sexual assaults, assault when resisting arrest etc. Yours would be on the lower scale of seriousness.
The issue if you do not accept the caution is that you will face prosecution and the outcome could be a lot worse where you get a formal conviction and a criminal record, rather than just a caution. So you will be taking a big risk if you proceed to prosecution instead of just walking away with a caution.
This is your basic legal position. I have more detailed advice for you in terms of the other rights you have based on your length of service, 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
