NC and trying to be vague but also give as much information as possible.
I had an ongoing dispute with my employer and raised a grievance on the advice of ACAS and other advisory bodies. The grievance was pretty much ignored along with further complaints to said employer about breaking the law and mismanagement. I subsequently left the organisation and believed that the issues had finally been resolved. However I have just found out that they have not which potentially will cause me a number of problems. I wish to take the matter further but I am not sure how. Will ACAS or CAB be able to help if I am no longer employed by the organisation? I am also considering getting the advice of a lawyer but not sure how to go about it. The organisation is also a charity and there are potentially much greater implications. Is it possible to make a complaint to the Charity Commission? I am not sure if it would count as whistleblowing (especially as I am no longer employed by them). Also, from what I gathered by looking online, the Charity Commission may not be interested in a workplace dispute, although I may be wrong.
I was willing to let the situation go due to the enormous stress it has caused but I feel like I no longer have that option. Also, I don't think it is fair for the organisation to potentially do the same to anyone else.
Thanks for reading, and if anyone happens to have any further questions, I will try my best to answer them without outing myself. I have never been in this situation before so I feel at a loss to know the best course of action.
