Less generous offer the next time? I doubt it; the company wants people to leave and offering less will not do that. Folks will ride it out to the bitter end. What was offered this time was not that great once it is taxed.
If Hans wants techs to go he could spend a couple billion and offer 4 full years of pay and insurance and the 60+ crowd would sign up PDQ and anxiously wait for their last day. Most of his techs are Union and with this contract he will pay that same money anyway over the next 4 years. Might as well get them out now and replace them with unprotected, lower wage employees or with contractors.
I agree with @WsnrYiV-1opg on this. Thought he was on point so I reposted his post as a thread.
