I am part of a 3 member start-up. When we started(6 month) ago we split the equity equally between us and signed a vesting agreement with a 1 year cliff.
We have been having some internal disagreements, and ego fights - it quickly became obvious the for the company to function properly one of us has to leave.
Now the other 2 partners are threatening to fire me. What happens to my stocks if I get fired?
I didn't reach the cliff, bit there is also a section in the agreement that says that if I get fired without a cause I get all my stocks up upfront.
That depends on the exact contract, however, the way most of them are written, you would lose your shares if you left before the vesting, whether it was your choice or not.
Figure out what (if anything you want) you want at this point. They run a potentially massive risk of being sued in the future by you if you claim you were forced out and they essentially used / stole your idea.
