Recent research project ranks IT job classifications as to which ones are the most demanding on a 24/7 basis. On average, IT professionals are required to be available to work 119 hours in each 168-hour week.
Sadly true, we as well as manyof our senior staff are awlys on, taking calls, requests for ad hoc reports for someone to prepare for a meeting, dealing with a security threat or just working on our endless backlog.
I think you need to be in IT in order to appreciate how tough a job it is .. they job of the CIO.
And CIOs never get enough credit for what they do. Working late nights and weekends, having your mobile on 24x7 and never getting enough budget to do what the business needs or to keep your infrastructure up to date.
