I'm not sure if this is a regular or legal thing since this is my first job but it's the second time it's happened now and I'm wondering if the problem is really the workplace.
A number of months ago, one of our coworkers just completely disappeared and didn't answer any of our manager's calls or us coworkers' calls. They did complain about working here but they're also the type to at least finish up hours they're scheduled to work to not burdern the rest of us general workers(it's a fast food place, and its beyond hectic if even one person doesnt come in without prior notice since theres not even barely enough workers to serve customers) so it was super weird that they didn't even notify us they werent coming back, which was why I was sure there was some emergency or something where they couldn't come in contact with us.
But now months have passed with nothing from them and another coworkers have gone missing in pretty much the exact same way. No heads on, no 2 week's notice, nothing, they just stopped coming in one day and haven't responded to any of our messages or calls.
So like, is this a legit legal way to leave a job? And is this a sign that maybe I should consider leaving myself? I agree there are a lot of things that bother me about working here but it's mainly from understaffing, there isn't any inhumane demands as far as I can tell. Pay is $14.75/hour as a somewhat-senior-but-not-veteran level worker for context
