Ah, I see. That is such a tough spot to be in, so my heart goes out to you!
I would agree with where @SeanO begins. So much of leadership is communication, consistency, and humility. And, as much as I don’t like the thought of it, as leaders, we have to be willing to confront someone when there’s a problem. This doesn’t always have to be a bad thing. I mean, confrontation is risky in the sense that the person you are looking to address may react badly, but in my experience, to let certain things slide can be even more damaging, esp. if you’re leading a team of people. One person’s negative influence can poison the morale of an entire team. But, I find - as I have been both giver and receiver of confronting conversations - that as I approach the person (or am approached) prayerfully, with humility, with a genuine heart that wants to understand the experience of the other, that more positive things come out of the conversation than negative. In other words, it is oftentimes worth it.
So, yes, I would encourage you not to flee/‘forgive’, but, in bold humility, to stand up and confront…meet him head on, not throwing punches, but asking the hard questions. Be willing to have a difficult conversation in the hope to resolving the issue at hand.
I hope this doesn’t sound condescending! I mean for it to be encouraging, to spur you on in the good work! I will be praying for a constructive resolution of this. Thanks for your letting us in on this little slice of your life.
