Buddy...the point is really, really not unlimited PTO.
NO ONE treated workers at scale like Google did in earlier decades. It was literally wild and unprecedented.
Engineers for many decades had unprecedented job mobility and bargaining power. Certainly not a bad thing in and of itself, but it's an outlier experience that's ending.
Unfortunately, companies don't organically and spontaneously decide to treat their workers well. Leaders need to fight for it...and most engineering leaders just aren't positioned to right now.
