It takes a special type of character to work in an Ops department. You need to be decisive & confident without being reckless & stubborn. You also need to be able to multi task meaning you can prioritise your work but still get everything done in a timely fashion so that the schedule you are supervising does not suffer delays. Another key characterisitic is having good communications skills. This is not a job for a shy person. Most Ops offices involve phoning people, updating them on current situations and involving your colleagues on duty with you to solve problems. Dispatch Resource Management is the modern way of describing the work that goes on in Ops. It can be a stressful environment so ask yourself have you got those basic qualities. These can all be developed over time as your experience grows, but you need to be sure you have these basic qualities.
My suggestion would be to contact the Ops departments of airlines that are based locally to you. Tell them your situation and ask them for a tour so you can get a first hand impression of what you're getting in to. Somebody is bound to respond to your request especially with the busy summer season about to kick off.
