Number 5 Psychic
Being Psychic would be a great Super Power to use at work, I mean you could do what your boss wants before he asks you and you could do it how he wants, eventually making you employee of the universe. Also it would get you to the top in society going from good job, to better job, to great job, eventually leaving you rich and successful. Word of warning though, it may be best not to tell your Boss about your "abilities" as he may not appreciate you reading his thoughts.
Number 4 Duplication
Everyone gets caught with those hard labouring tasks like, assignments and shelf stacking, if only there were more people helping. With Dupkication, you would be able to get your work finished in no time and still take all the credit. This however also has its share of draw backs such as the case of, what if you forget who the real "you" is, or even if one of your clones gets you fired. You could also come across one of your clones making out with that co-worker you were meaning to ask out.
Number 3 Telekinesis
The reason why Telekinesis is so useful, is because it can be easily underused. In X-Men, Jean Grey uses her telekinesis to Save Mankind and Stop Magneto, but it could also have a more realistic useful purpose like; picking up your bag you left in the lobby, brining the item a customer asked for without leaving them or just stacking shelfs while sitting down. However you use it, Telekensis is very useful in the world of work.
Number 2 Strength
Every Career usually involves the occasional "Heavy Lifting", whether it's carrying heavy boxes or carrying a customers shopping to their car. Super Strength would be a great asset in work.
Number 1 Super Speed OR Time Manipulation
I couldn't completely decide between these two, but since they would be useful for the same reasons, I think they both deserve the top spot. Need a report completed? Deadline approaching?, not if you could freeze time, or had Super Speed. Imagine racing through your work within microseconds and then taking the rest of the week off. Also These abilities would prove most fun and useful outside of work as well for a number of reasons.
