Here is my advice for young people joining the workforce:

Don't be helpful. It's the worst mistake you can make in an office environment. All of a sudden you will be a "go-to guy" for all sorts of minor computer-related dilemmas and the performing of minor favors. I made the mistake of being too helpful my first month working here and it took over thirty (30) months for me to get back to square one.

Make sure the CC: everybody in your office for every email you send. What this will do for you is get people to start ignoring your email which helps you cover your ass. For example, once your supervisor starts ignoring you, send him or her a message like, "Unless you inform me otherwise, I'm going to assume it's alright to take the rest of this month off starting on the second." When you get back, simply inform them that if they had been paying attention there never would have been any problems.

Do not learn or attempt to learn to use a computer. Most work these days in done on computers so if you don't know how to use it, they can't make you do any work. At the very least, avoid learning MS Excel. This will make you feel justified in making people who didn't take my first piece of advise seriously do rudimentary spreadsheet work for you.

If you ask someone to do something for you, make sure to be as unclear as possible. When they ask for clarification, ignore them until they actually finish it and show it to you at which point you suggest a bunch of changes that are equally vague as the original assignment. After a few rounds of this, accept something that looks virtually the same as the project as it was presented to you originally. Make sure whoever is doing this is under the impression that each step of this process needs to be done immediately and perfectly then ultimately end up contracting someone out to do it anyway. There's no reason to do this, really, but the power trip does feel good.
