Communication skills are important, but you need to know when to shut the fuck up. That's what's universally important and entirely true. Instructions are never perfect. It's whether you can get the job done anyway, once you know what is being asked of you, which is mostly a one time initiation. Ever see someone repeatedly asking and questioning what is being asked of them? That's someone who is going to struggle for…
Work is no excuse to talk. I understand that there are people who prefer to work in silence, concentrating on nothing but the task at hand, but the suggestion that everyone should be like that is idiotic. There is a wide variety of people in the workplace; we aren't all the same. The idea that office hours should be limited to work and nothing else betrays who we are: living, sociable human beings.
Talkers truly underestimate the bandwidth it takes to engage someone properly, and if you're not engaging someone properly, your presence is just insulting.
If you're in an open office without walls or cubicles, and people kept talking to you, you wouldn't get anything done. Their excuse? That they're living, sociable, human beings. Well, tell that to your boss.
Think of a busy kitchen. People don't talk beyond the signals required to advance workflow. Of course, everyone can chat when they're not busy. But that's also when the business isn't making any money. Restaurants close to take you off the clock.
Think of all the jobs that require focus, like programming and writing. Think of all the jobs that are so much easier with focus, like almost every job.
Of course, if you like to talk, just get a job that requires it. Waiters get to talk while they wait for customers, and get to talk with customers. Journalists, teachers, lawyers, consultants, entertainers.
And my suggestion was to know when to shut up, not that everyone must work in silence. There is a time for communication, and for your presentation skills to shine. It just isn't "whenever I feel sociable because that's who I am, yo". But that's school! Get it?
And all this, they DO NOT TEACH IN SCHOOL.
