I think maybe they really don't want to lose 25% of their engineering, sales, and field support personnel, and are hoping to just run out the clock.
Not only do they not want to lose their workforce BUT if ANY of their staff members have adverse effects the company is legally responsible for mandating the vaccine!! Big Pharma not responsible HOWEVER the employer WILL BE accountable for mandating it!! They don’t want the massive lawsuits that are possible!!
Exact same story with the defense contractor I work for. They’re kind of looking the other way for as long as they can because they know they’ll lose a lot of us if they try to push a mandate.
