The worst thing for part timers in the contract is the absence of 22.3 jobs that will be opening this contract.
The union is more or less letting them put an end to new 22.3 jobs by filling them with 22.4 driving jobs.
Also, those GWI are getting slimmer and slimmer with inflation. What's the point to part time anymore? No 22.3's no hours no pay. You can't live on health insurance.
