As I say grand jury duty is often not every day, you can always take your PTO, and there are always nights and weekends. A company can always keep paying your base salary but, as you say, there could be longer term consequences.
And the case upthread is obviously a retail manager being stupid but I also assume there is no obligation to pay hourly employees for hours they don’t work or for tips they didn’t collect.
> not every day
Yep
> can take your PTO
You can, but if salaried you usually shouldn't, ignoring any particularly malicious employers and social contracts around the outskirts of the law.
> No obligation to pay hourly employees, tips, etc
Yeah, if you're not salaried you're screwed. PTO might cover a few days, but if you have a month-long trial and need money for rent then my understanding of the law is that serving as a juror will make you homeless unless the courtroom is willing to extend some compassion for your hardship.
