Just my 2 cents here. O'Brien and staff should realize their are two parties. The truth lies somewhere in the middle.
If O'brien wants to punish the company, then all should realize they may be looking for a new job. A strike would decimate UPS, but would not destroy it.
It would take a decade to come back, but without a union to deal with, the company would rebuild easily without $50/hr, pension contributions, insurance premiums, etc......
Their employee overhead would plummet and would be rebuilt without all the headaches and drama every 5 years.
The would become just like any other at-will employer.
Jobs, like the ones UPS has provided for decades, don't grow on trees. Try to find another with such benefits.
I worked there for 30 years, and thankful for the check direct deposited in my account each month.
Most, if not all, active employees don't think about their long distance future.
One day you will, maybe sooner than you think if O'Brien is more than just talk.
And no, pretty sure my pension is safe, to a degree. In order for UPS to breakaway from the union.......there is a law requiring a buyout from an employer with active retirees to maintain some or all of their benefit (pension withdrawal liability), this would be a big number for UPS. But then they would be done with any more contributions and no help for active employees going forward.
Bottomline, I believe both sides should bargain with respect and in good faith.
