Your nontechnical co-workers will use you as personal tech support for their home PCs
Your co-workers (in addition to your friends, family, and neighbors) will view you as their personal tech support department for their home PCs and home networks. They will e-mail you, call you, and/or stop by your office to talk about how to deal with the virus that took over their home PC or the wireless router that stopped working after the last power outage and to ask you how to put their photos and videos on the Web so their grandparents can view them.
Some of them might even ask you if they can bring their home PC to the office for you to fix it. The polite ones will offer to pay you, but some of them will just hope or expect you can help them for free. Helping these folks can be very rewarding, but you have to be careful about where to draw the line and know when to decline.
Vendors and consultants will take all the credit when things work well and will blame you when things go wrong
Working with IT consultants is an important part of the job and can be one of the more challenging things to manage. Consultants bring niche expertise to help you deploy specialized systems, and when everything works right, it’s a great partnership. But you have to be careful.
When things go wrong, some consultants will try to push the blame off on you by arguing that their solution works great everywhere else so it must be a problem with the local IT infrastructure. Conversely, when a project is wildly successful, there are consultants who will try to take all of the credit and ignore the substantial work you did to customize and implement the solution for your company.
You’ll spend far more time babysitting old technologies than implementing new ones
One of the most attractive things about working in IT is the idea that we’ll get to play with the latest cutting edge technologies. However, that’s not usually the case in most IT jobs. The truth is that IT professionals typically spend far more time maintaining, babysitting, and nursing established technologies than implementing new ones. Even IT consultants, who work with more of the latest and greatest technologies, still tend to work primarily with established, proven solutions rather than the real cutting edge stuff.
