Did I get ghosted or is commercial work dead?

So I got a job as a “production intern” for a commercial production company, turns out it wasn’t an actual internship it was literally just a PA job, which I'm not complaining about because any experience is better than none. But the thing is I’ve not heard back from them since the first project I’ve worked on. Am I supposed to reach out to them for more work, or is there just nothing happening right now but they'll call me if they need a PA? For reference I’m in New York, NY
