I say this having attempted to run a "egalitarian" team for well over a decade now. I've learned some lessons along the way. Basically reality doesn't matter to most people - perception does. If it's perceived that one employee is getting "special treatment" the rest demand it, deservedly or not. It doesn't matter if that employee does 5 times the work.

I still operate on the "Get your work done, and I don't give a shit if you're on the beach while you're on Slack with me" premise, but I understand this is only for a very select subsection of employees. The rest simply cannot handle it, and most companies take the easy/lazy way out and simply try to treat everyone as an equal as it results in far less drama. I think this is completely unacceptable, and high performers deserve to be treated as such.
