Thank you all for your support in this.
I am not specifically valuable in a situation that affects hundreds of people unfortunately.
Just so you know, I did a stint at one of the largest outsourcers in the country. If a company "cares" about their employees they will provide a take all policy with a commitment (sounds like one year for you) with retention bonuses for key employees. When that year is up the layoffs WILL happen. 90% of your current co workers will be gone. The business model is too low margin to exist without transferring the work to their leveraged service model in low cost delivery centers. They get paid extra to make the transition work, but does not make sense to retain high paid employees who are loyal to their customer instead of the new firm when the commitment is up.
Do you have a legal plan at work? Worth getting some advice. Are your parents alive? Maybe 2 months of FMLA care giving will get you to the finish line with more safety. My guess is they just want to reduce the headcount. The savings from denying you health care is not worth the risk of a discrimination lawsuit when you are so close if they are not grandfathering you in at the new company.
