Could you please explain why you have a grudge against the new owners of the company or how they have mistreated you?
Did you receive a severance package or any type of compensation when you left?
Considering selling the recipe on EBAY is not a very good option if you wanted substantial and reasonable compensation.
I don't want to go into the details of how they violated my employment agreement here but that's what happened. In order for the company acquisition to go through, all of the company executives had to sign an employment agreement promising to stay on for at least one year. Two months after signing the agreement, they violated a clause in the agreement. They did something they should not have done and they knew it. I could have sued but because it was my families business before the acquisition and there was already turmoil amongst the hundreds of employees that I grew up with, I let it go. I got a substantial amount of money when the company was sold. I also received one year compensation as a result of them violating my employment agreement. No other agreements were signed after that. I even tried to negotiate getting more money by offering to sign a non-disclosure, non-compete and non-disparagement agreement but they declined. They didn't want to or couldn't pay me more than what they already paid me.
