Do You Unix?
If you don't have this hot skill, you are at a serious disadvantage in the marketplace. Despite Microsoft's best efforts otherwise, most enterprise systems (especially in the financial or telecom sectors) run on some version of Unix. Whether it be AIX, Sun Solaris, HP-UX, or some other flavor, Unix knowledge is key. I can't emphasize this enough. Batky-Howell offers some great Unix courses; see if your company will send you. If they won't, take it yourself. This is a skill that more than pays for itself. They say that taking your MCSE courses can increase your pay by $15K a year. Well, knowing Unix thoroughly can take you much farther than that.
