Question

A certain nonprofit employed me and made various commitments to me, some of them in writing.
During my work there I was exposed to many illegal acts being done there, as well as acts whose legality may be in a gray area. But if the donors knew what was really going on there, they would be in great embarrassment and in serious trouble.
They present themselves as good people doing good, but on the ground serious injustices are being committed there, certainly toward me.
At a certain point they informed me that my employment was terminated, but in my view a huge portion of my wages was withheld from me unjustly, and as I understand it מדובר in hundreds of thousands of shekels.
They are dragging things out and do not intend to pay me unless someone compels them.
I consulted a rabbi, and for several reasons it seems to me preferable to sue in civil court and not in a religious court.
A rabbi instructed me that this is permitted.

Suing in court is a practical option, but it involves enormous financial expense, which I do not have. The years in which I worked and was barely compensated have left me completely impoverished. I need a livelihood now, and I was counting on payment from them, and now I am in enormous trouble. Also, every claim requires proof, etc. I do have proof, and I am not making anything up, but it is still a long process, draining, emotionally exhausting, and expensive.

My question:
I have a journalist friend who is God-fearing.
May I tell him my claims, and he will edit it and ask for evidence that satisfies him? Presumably he will contact them to request a response, and likely publish that as well.
I assume that when they understand that their actions are about to be exposed to the public eye, they will back down and try to reach a settlement with me, and I will ask my friend not to publish in exchange for their actually paying me.
And if that does not work, then all the more so, let the Jewish people know where its donations are going and what is being done with them…
In any case, they will be given a fair right of response to explain their actions.

The option of going to court is still not ruled out for me; perhaps this will just help me shorten the process in terms of time, money, and resources, which I am currently lacking.

Is it permitted to do this?
Of course without lying, without adding even the tiniest incorrect detail, and of course with a right of response?

I would very much appreciate an answer. My resources are running out.
Many thanks, honorable Rabbi.
