That carries a lot of assumptions - e.g. that the workplace a person is in allows and rewards those things. Some do, some don't. If the workplace doesn't, that's not the fault of the individual employee. It's also a bit weird to look down on "double dipping" at the individual level but we work in an industry that aspires to do as little as possible and maximize profit at the company level as much as possible. Many of our employers have or want to have business models where they sell software subscriptions and maximize the revenue for writing the software once. If your employer manages to sell 2x as many subscriptions for the same work, then they're smart and have a great business model. If a person figures out how to juggle several jobs, they're double dipping. Note: I was brought up to believe in 40 hours work for 40 hours pay, etc. I still believe that, and I wouldn't short my employer in order to hold a second job. But I have held full time jobs plus doing writing on the side. If the view is that a salary entitles an employer to every single productive second of my time, that salary better be amazing.
