Is it worth hunting down this type of behavior? I honestly don’t have a problem with someone having a side gig, but when it reduces their attention to just being able to do the bare minimum asked of them it seems very unethical.
I don't see how you could possibly give your full attention to one job when working for multiple at the same time.
I also wouldn't want an employee accidentally committing proprietary code/logins, which could be a huge security issue.
a 'side gig' to me means working on it outside of working hours, not at the same time.
This is just dishonest.
