You should give your employer a 72-hour notice at minimum

All the people who come online and say things like, your employer can fire you today. You shouldn't give them any notice before you leave. That advice. You could be leaving money on the table. And this is coming from someone who quit a job, gave the employer up to 72 hours notice prior to leaving and ended up getting an extra week's worth of pay. Every state has their own labor codes, so you're gonna have to check which state you live in, but I live in California and in this, it's great. Golden State employers are required to give employees their last paycheck on their last day. No grace period. Weekends don't count. None of that. If I gave notice on Monday that my last day was gonna be Friday, the employer is required to give me my last check on Friday. And if they don't, every day that I have to wait for my paycheck, the employer has to give me a full day of wages. Even if you are fired, your employer's required to give you your paycheck on the last day. And if not, there's waiting penalties. And sometimes these things are just like administrative errors. It doesn't mean your employer is being malicious on purpose. It could have just been an oversight. The thing is in California, no excuses. You should give your employer a 72-hour notice at minimum. If not, and if your employer doesn’t pay you on your last day, you may not be eligible for waiting penalties. In Colorado and Montana, they require you to pay the same day. If not, there's penalties. In Massachusetts, there's treble damages, meaning three times the unpaid wages for willful violations. Arkansas has doubled the wages, but Missouri, if you're not paid within seven days of written demand, the employer could owe you additional wages for up to 60 days. The moral of the story, and also because it's professional, the right thing to do. You should be giving your employer notice when you are terminating employment.
