I work full remote. If they ask me to RTO, I quit and retire. Game over, man.

But, given that, "5 days a week RTO is just beyond the pale"? No. That's just normal for pretty much everyone on the planet.

Top talent? If they're not willing to negotiate on 5 days RTO you need to adjust your ideas of how marketable you are, you're not top talent and you're not a trusted adult, you're a human resource.
