There are a lot of news articles about "back to the office", but they recirculate the same bad ideas. Let's provide some new ideas for the media to circulate. It may also have the effect of making the office less terrible.
I would like my work computer to do Windows updates lightning quick in the office. It currently takes weeks, in or out of the office. Stopping in for a day makes no difference, so there is no point. Now, if there was a point, I would go in.
What would get you in the office?
Given that they also talk about finishing their work with nothing to do, I'm guessing they work one of those jobs that doesn't actually need so many employees but has to have them or are held back by the lowest performers.
The idea of "completing all my tasks" is a silly one to me, since my product has an endless stream of work where we can't do all the things we want to do. If I managed to finish all the things I personally planned to do, that would mean nothing as that's just my personal plan and there's a virtually endless backlog. This has been the case for every job I've had as a software engineer.
Most employers I think pay for time, anyway, not tasks. Even when salaried, it's a salary intended based on time you'd generally work. And if this wasn't the case, many people (myself included) would be penalized for delays.
