The Infosys managed services cut over came at a bad time for VZ, it was announced the same day as the ESP in 2018.
Originally, HR said - go with Infy, ie. re-badge, or it's a resignation (Yes, that is what was said, proof is from an audio recording of a meeting between emps and leadership). No package, no nothing.
There was of course huge pushback and a lot of it from all directions. VZ eventually allowed emps to take ESP in lieu of joining Infy. There were bridge payments and certain guarantees.
Maybe Leadership has learned from 2018 and will handle this transition better - we'll see.
