I'm sorry to hear this, but the same thing has happened at Atlas as things heated up.
Sucks for the new guys, but there's a lesson here! When you accept a position in an organization during times like these (negotiations) THERE WILL BE BLOOD.
The good news is that this means your team is getting to the company. They're feeling the heat and lashing out.
Good for you. Do not let up. Hold the line and get the contract you deserve.
