laravel problem running background job in php

I have the following job:

    public function handle(): void
    {
        //
        sleep(5);
        echo "hello!";
    }

Following controller:

    public function index() {
        ProcessPodcast::dispatch();
        // return redirect('/api');
        echo "finished!";
    }

and route:

Route::get("/job", [JobTest::class, 'index']);

My problem is basically that the job is not executed in the background as expected. I used the command php artisan queue:work and accessed the /job route that triggers this job, and what happens is that the page takes 5 seconds to be displayed because of sleep(5), but what I expected is that this delay would not occur and it would only be executed in the background.

I’m trying to use redis for this:

QUEUE_CONNECTION=redis

No error is displayed to me in the terminal, does anyone have any idea what might be happening?
