I work in 911 dispatch, exact qualifications and work conditions will vary from place, but often you don't need much more than a high school diploma/GED, basic computer literacy, and acceptable typing skills, and of course the ability to keep a cool head and deal with emergencies.
Technically, I work slightly more hours than a regular 40 hour week, but I have more days off overall, and especially on night shift you can often count on having a decent amount of downtime where you can work on pretty much whatever personal stuff you want between calls as long as you can put it down when the phone rings.
And the pay is going to be better than minimum wage, not that you're gonna be making a killing, but you'll also have access to pretty great benefits and job security.
It can be stressful and not everyone is cut out for it, but if you are I think it's a pretty great gig, I've been doing it for 8 years now. There is a lot of turnover from people either getting burned out or just using it as a resume builder to move to other public safety sorts of jobs, but that means that basically every dispatch center in the country is almost constantly hiring.
