I just read a whole article (this one) about a guy that had to switch to a single monitor because switching to a tiling window manager made it hard to live with more than just 1 monitor, so allow me to doubt that your WM is actually increasing your efficiency.
But even without that, no you are no. If you need to switch between virtual desktops to, for example, see the code and see the website renderer by the code, it is an highly inefficient process.
So unless your single monitor happens to be a 44" 5K monitor, I would 100% fire you.

I think the word "imposed" made it pretty clear that I actually do not have the choice.
Switching workspaces is as easy as moving your eyeballs, at least in a tiling wm. It's no different workflow wise, except it costs hundreds of dollars less. You can literally only look at one monitor at a time. Very, very few people actually have a need for more than one. The majority of people using more than one monitor are doing it because it makes them feel like hackerman, because their boss imposes a workflow and environment on them, or because they can't be bothered to try to make their environment more efficient.
If you believe it so strongly that nothing can possibly change your mind your believe is irrational, doubly so considering you admit your choice of operating system gimps productivity yet you still choose to use it. If you'd fire someone for using a different workflow than you as a heuristic for their productivity you have no business managing people.
