What if I secretly kept coding at home?
People who want to complete tasks with ruthless efficiency will struggle immensely with the waste at union (and government) orgs.
Sorry for the rant, but you're question isn't worth worrying about because people that would want to work from home wouldn't be working in a union shop that barred work.
The union working rules make sense for the company. It's not sustainable to work that much. Worker burnout and churn is bad for the company. Fostering a culture that forces people to work until they drop if they want to get ahead is toxic.
