Being jailed or otherwise detained for any amount of time, sure. But otherwise, working through the legal process wouldn't be something a regular employer knows about. You would have more errands to run than usual perhaps, that's about it.
Another example: as a programmer, if I run into legal trouble with the IRS and they sue me, or if my neighbor sues me for damage to their property, how would my employer know?
(I'm not saying it's good that employers might not know this. I'm just baffled by the article taking it as a given that practically all employers would.)
