From the supplemental agreement regarding the personal savings plan (exhibit G, available at uaw.org/gm2023)

“The Company shall increase its contribution to an Eligible Employee’s Account from 6.4% to 10% of each such Employee’s Eligible Weekly Earnings with such increase to be implemented by December 31 2023, with contributions made retroactive to October 23, 2023”

It’s a straight up contribution. For every dollar paid in wages, the company also contributes ten cents to the employees 401k. No employee contributions are required.

You’re welcome. The last part of the morse code says “remember to always drink your Ovaltine”

It was released in a limited run by Tiki Tony . The glasses came in pairs and have a COVID theme. I believe the Morse code reads “after the plague came the Renaissance,” as well as another phrase I can’t recall at the moment.
