I am a volunteer in an organisation, and running a very successful part of it with a great team under me.
Another part of the organisation is really struggling and the person who is my equivalent in that part has asked higher up in the org for some help. When it was suggested that I take over her part of the org too, she accepted pretty quickly - no resistance or hesitation (in fact, we all had a meeting to discuss the way forward and she caved in on this before the meeting had even properly started) - but I asked her to stay on as my "assistant" to help me as I found my feet.
I've been there a few weeks and it's a pretty toxic environment. I've tried to go about it in a fairly business-like fashion; identified strengths and weaknesses, drawn up a development plan etc. At every step of the way, I've asked the opinion of my predecessor on my findings and suggestions, and to my face she has agreed with everything I've said.
Of the other six-or-so volunteers, one is quite new and seems very genuine. The other are all entrenched and, frankly, I blame for the problems their part of the org is facing. The new volunteer is telling me that behind my back, my predecessor is undermining and contradicting what I've said, and saying things like how she feels ousted, doesn't need anyone's help and I've come in and upset everyone. This last part is probably true, and I'm OK with that. If this was a work environemnt they'd all be on PIPs, but that isn't really an option.
The new volunteer has no reason to lie to me about this and I believe her. The problem is, as she's alone it will be very clear who I've heard it from if I confront my predecessor as the others are all "in cahoots", for want of a better term.
I'm happy to hear constructive critiscism from people and I acknowledge that I'm blunt and to-the-point, but they really need a shake up which is the reason I was brought in, to - quote - "ruffle some feathers".
If my predecessor openly said the things I've heard to my face, I'd ask her how she can objectively claim they don't need help when they are struggling and weak by just about any metric. I'd happily hear her out, but I honestly don't think she can have much of an argument. But to my face, she agrees they needed help.
How can I confront her and have this discussion, without betraying the other person's confidence? I suspect it's a little bit of regret that she's opened this can of worms by going further up the organisation, but that ship has sailed now.
