Events and Jobs Not Firing from inside Laravel Event Listener

I have an event listener that creates and saves a pdf file from a record in the db.

This process completes correctly, then I log the results and wish to fire a Job or another Event and neither will run.

If I run either from a controller they execute flawlessly.

handle method looks like so:

/**
 * Handle the event.
 *
 * @param  SaveRecordPdf  $event
 * @return void
 */
public function handle(SaveRecordPdf $event)
{
    $record = $event->record;

    if ($this->service->publish($record)) {
        Log::info($record->published_filename . ' was stored successfully.');

        // fire publish job
        PublishFile::dispatch($record);

    }
}

Is there any known reason why this would be happening?
