When to bring claim of

Please look at my information. I have been in a family business for 12-14 years. The majority stockholder has used a variety of intimidation and actions to keep control of every aspect of the business. He has used "squeeze out and freeze out" tactics to bend every other shareholder to his will. He used company funds to get a loan for a building and property then made sure no other shareholder/employee could have a stake in the property.( he created a 2nd company that owns the building and property) Then had the main family business pay off the loan for the building and property thru rent payments. He also used company funds ,equipment and assets to start a 3rd business and tried to convince us minority shares that we had to invest our free nonpaid time to own part of 3rd business. Also forcing employee/shareholders to work on the building to create a "party rental" space that is mainly use for his 3rd business and personal usage. when any minor shareholder/employee has disagreed with his actions , it leads to verbal abuse, intimidation and usually be fired by him and the locks changed on the building. There has also been many physical altercations thru out the years. There has been fraud and false accounting and other deceptions he has committed. He has lied about what % of stock each of us would owne in the 1st "family" business. For these and several other reasons, I feel I have a great case for breach of fiduciary duty and wrongful termination and other claims.
