Disclaimer: I'm not an IT guy nor I work for an IT company.

There is a third option. You are working and staring at the screen for the whole day, even without breaks, but you can't actually focus on a single problem or piece of work, because the manager keeps distracting you.

I work for a small company, and as a consequence, I have a quite wide area of responsibilities.

I can't really focus on the bigger tasks (like creating user's manual for the new company product) when I'm supposed to drop everything if there are any unanswered emails from the client.

And learning midday that "Hey, man, the newsletters have to be ready today! And the website content needs to be updated before you send the newsletters!" is a very likely possibility, too.
