> One problem is that such people will the occasionally not get the job done, but have committed fully to the “part time” part, so they’ll continue a low effort schedule but not hit the targets.

If they weren't highly productive, they'd work the 40 hours and not meet their targets. Seems like the same situation except manager wants a butt in a seat.

> Other times they’ll get their parts done but be really har to get a hold of for other employees which might impede them.

Then they aren't really getting them done. There should be docs and enough information for someone else to interact and build off their work. The sync culture of butts in seats promotes high levels of tribal knowledge and over the mid to long run hurts velocity.

> Sometimes you’ll just have issues with other employees being angry that they seemingly make the same but put in a lot more effort which tanks the moral of all the other employees.

I gotta say, too bad for them. This comes from a butts in seats culture, which will drag everyone down to be the lowest common denominator.

You'll have a department where you have 90% normal devs, and 10% high productivity (per hour) devs. Force those 10% to be butts in seat and they are gonna go somewhere else.
