I sent a private wats app message to a colleague, there was a joke in the context of conversation where the person said they found it funny and understood the irony of it and my intention. For someone who did not know the context, it could be perceived differently.
7 Months later, when there were working difficulties in relationship with this person, I was informed by my boss that the joke i made at that time had been reported to them.
I was given informal action to this and accepted this and was closed by my boss, i was also informed the person was showing the joke to other colleague and was asked if i wanted to raise this as a concern as seemed malicious and to discredit me.
this was discussed, the person claimed someone had put this up to them and also my joke had caused offense 7 months ago. although i did not believe this apologized, my concerns of being discredited were left as resolved from this meeting.
2 months after this, the person is having their own conduct issues at work managed through processes, they share this joke with people external from my employer, who have been informed and the same incident is now being formally investigated as it could bring my employer into disrepute if shared on social media/press which the person has threatened to do.
is this legal?
I know the obvious one i shouldn't have made the joke (even though private and was a context). I already regret this.
If the content of the joke had been reviewed by my employer and informal actions were taken (which is recorded).
can the same joke now warrant formal action, because someone has shared it to a different audience (I have no control of this).
advice please
