The other powerful thing about being able to do everyone else's job is that you, personally, gain a lot of leverage, and in a lot of different ways. Someone else needs a favor? You probably know how to deliver. Something's on fire? You probably know what to do next, or at least who to call, no matter what's on fire today. Someone isn't budging on something? You might not have any bigger of a lever than anyone else, but you probably know exactly where to position yours, and exactly what it'll do when you apply a bit of force.<p>It's useful.<p>And then there's times like getting to charge your client $300/hour to drop stuff off at FedEx. Because <i>you can do that</i> and <i>you're here</i> and <i>you'll get it done right</i> -- no one needs to explain the idiosyncracies of this particular deadline or package contents; you've got it.<p>Even if that's not normally a senior consultant's job.
LOL! My bosses used to tell me that I need to learn to be more `rude` and not just do what others says because I can. I have learnt a lot and one of the biggest is to say NO, in big Uppercase—I can do anything for work but I won’t do that, NO, I won’t do that.<p>Sometime, I still do and I like the fun and thrill of locking in a hotel room after a meeting and coming out in lot less days these days (pppppsssstt, because of AI) and get into the next meeting showing off what can be done that was discussed 48 hours ago.
You don't do these things because they benefit your boss. (They might happen to, but that's not the point.)<p>You do them because they benefit <i>you</i>.<p>Not going to benefit you? There's lots of ways to say no to a back-channel request. Not a back-channel request? Then I guess it's not someone else's job!
