Full time employees might have core hours and then flexibility outside of that. Otherwise, you do your work as quickly as possible and then outside of that is free time. Unless they are reusing the same work at two jobs, they likely are not double dipping. If their metrics are fine, there is no reason for a manager to care other than wanting to micro manage someone’s life.
To be clear: If you Tell two employers that you are working for them from 1pm to 2pm, you are double dipping. The title of the article doesn’t line up with the content. Having a second job that you work outside of the hours / commitment of your first job is fine as long as you didn’t agree not to do so with your first employer. If you want to work 9-5 earning 6 figures in a WFH white collar job, then go out and get a night job at Target and are somehow able to succeed during your first job the vast majority of employers aren’t going to give a shit. The reason employers give a shit is this is a largely fake narrative. Studies have shown the 40 hour work week is too long. People working two jobs cannot keep it up for long and be as good at their jobs. Second, people are conflating having 2 separate jobs with working two jobs at the literal same time. Working 9-5 at two companies and juggling email and meetings between them. The article touches on this, but I completely disagree with the author. So much of business is based on collaboration that having to wait for a peer who is doing work for another company now costs the first company for every person that is waiting on them. Maybe 2% of my work can be done without a single other co-worker being involved in some way. During regular business hours the expectation is that you are being paid to work and collaborate with your co-workers on a regular basis outside of normal PTO etc.
