Absolutely, indeed frak being productive. It's a Ponzi scheme, you have to keep grinding so you can land your next job that might be slightly better (and often is not). And we're talking in your free time, not even during the work hours.
How about some new propaganda?
"Work maximum 5h a day and the other 3h you will donate to your employer if they are kind and give you good atmosphere and money"?
How about that one, eh?
