I'm in the unfortunate position of being someone's boss, and I had to have a frank discussion with an employee who wanted special treatment about how replaceable they are. That conversation sucks, because if I had more autonomy, I'd grant more privileges to everyone (i.e. more WFH).

My advice: don't make yourself replaceable, your employer isn't worth it. Instead, make yourself an attractive hire, so you can always jump ship if your corp pulls something (and they will).
