Document EVERYTHING. As soon as you suspect something is amiss. I can not stress the importance of this enough, your families financial future may depend on it. Carefully document anything that you feel is inappropriate, unfair, discriminatory and/or illegal as soon as you suspect anything inappropriate. Refer to your shareholder agreement, any employment contract you may have, workers rights under applicable labor laws and your rights as a shareholder.
If you have any “agreements” be sure to get them in writing. Don’t believe anything that is said to you verbally, until you have it backed up in writing. Document the conversation and send it to the person involved and ask them to confirm the documented conversation. This will be great help when the litigation commences. If possible, get backup copies of email and any relevant corporate documents.
