Get paid for doing multiple roles
In my case, I perform the duties of a facilities manager, electrical engineer, participate in server room design and build, set up servers, network equipment, understand databases, software development cycles and a few other things which are known to be critical for company operations. Basically, I do the job of several people and have presented myself as a "do more with less solution" to the company. After 20 years in the business it gets easier to do. Oh, and by the way, make sure you understand what are the cost centers and profit centers in the company. Ensure that the profit centers can vouch for you in times of need.
