Although I feel the railroads need to modify their sick day policy (three days notice is ridiculous) and could have allowed for paid sick days on top of their three weeks of paid vacation (seven for managers) It's hard to shed too many crocodile tears for them. They already have a golden pay and benefit compensation package without the paid sick days.

All the republicans claiming to "be for the workers" and criticizing Biden were just playing politics.
