Is it correct to say "I left work already"?
I wanna sound casual but you tell me what else could I say.

Question

Answer

Yes, you could say that and would be understood. You could also say the following:

1. I'm not at work anymore.
2. I'm finished with work for the day.
3. I already left work.
4. I'm already done working today.
5. My shift at work is already over.

Answer

You can - it's a typically American way to say it. It would be a bit more normal otherwise to say "I've left work already", putting it into the present perfect.

Answer

It is correct to say that. As to what else you can say - you can say that you left the office, or you're not at work already, or that you're already at home. Whatever you choose, there's quite a number of options.
