Perhaps in other industries this might be a decent tactic, I don’t know - but in a business admin role you’re almost guaranteed to get one of the following responses.
1a. 'Cut Down To Size’
Response: “Your job is just to take minutes. You can manage that, surely?”
OR
1b. 'I didn’t know you were an idiot.'
Response: “Oh. I thought that was something you could help me with. I’ll find someone else”.
Result: From now on you won’t be given any other opportunities, because you’ve declared yourself incapable of taking on responsibility. Essentially you’ve primed yourself for task demotion - when allotting out tasks, you’ll get overlooked for the interesting ones because obviously you’re not skilled enough to handle anything more challenging.
The boss might be doing this to be vindictive, but it’s also possible they’ll do it because they genuinely like you and don’t want to stress you by forcing you to do anything you aren’t capable of - and you’ve just made it clear that they can’t assume you’re capable of anything.
2. 'Did you just tell me how to do my job?'
Response: “How about you leave those kinds of decisions up to me?”
Result: Manager now thinks you think you can tell him what to do. Manager will now consider you with latent hostility, which may not affect your day-to-day relations with him/her at all… the first you’ll know about it is when you need him/her to stand up for you and, inexplicably, it doesn’t happen.
3. 'Your Faction with Manager has Just Decreased.'
Response: curt “I see.”
Result: Manager will now complain to upper management, HR, and anyone who’ll listen that you’re lazy and ‘not a team player’.
…
I’ve seen managers do every single one of these - though not to me, fortunately. Managers come into each other’s offices and talk frankly, so as a PA I’ve seen a lot of what goes on behind the scenes.
It really makes my appreciate the fact that I have a really good boss at the moment … though I still wouldn’t want to push my luck by saying “I think you’d be much better at that than me” when she asked me to do something.
