Workers are a must for any minimally sophisticated web application. You cannot degrade HTTP response time (and whole app server performance) just because you are performing work synchronously before the request finishes. Similarly, if the work you are performing has any value for your business, it must be retryable, and the queued items must be safely stored (i.e. don't use a single Redis server - use something distributed like SQS instead). All of that calls for a 'proper' architecture. I'm not talking microservices or anything fancy - just a webapp/worker/db separation and the like. Which is exactly what dedicated server (or DigitalOcean) users tend to lack at early stages.
