As much as I'm capable of liking any job, I do like this one.
Funny enough, a big part of the reason I took the job was the same reason you cited, I was working in a warehouse, on my feet, carrying boxes around all day, and being able to sit down in the air conditioning sounded really nice.
Every dispatch center does things a little differently, but where I am we work 12 hour shifts on a 2-2-3 rotation, which is fairly common
So this week I'm off Monday and Tuesday, work Wednesday and Thursday, then off Friday-Sunday
Then the next week it's the opposite, and Wednesday and Thursday will be my days off.
I love that schedule, I never have to work more than 3 days in a row without a 2 day break, , I have days off during the week to get stuff done, and every other weekend I have a 3 day weekend, if I plan my vacations right I only need to take 2 days off to get a whole week
The one I work at isn't union, which has its pros and cons. Pretty much all the surrounding counties are union though, which helps keeps our wages competitive. I think most of the others around me make slightly more than we do, but one of the first concessions that tends to get made in contract negotiations is mandatory overtime, so since we aren't union we don't have that. If you do end up somewhere with mandatory OT, usually that means staying for a few hours after your shift ends as needed, not coming in on your days off. I don't mind working 12 hours, but anything beyond that feels like too much, so I'm kind of glad that's not something we need to do.
It can of course be mentally/emotionally draining for all of the reasons you're probably thinking. I don't think I need to list all of the horrible things I've gotten calls about, or the kinds of unpleasant people I've had to try my damnedest to help. People do of course get burnt out on it.
And it does feel good to be helping people, but if you're on Lemmy I'm sure you're not totally ignorant of all the issues that exist with policing, mental healthcare, etc. so you do also sometimes find yourself wondering if what you're doing actually is helping.
Overall, it's a good job, I do like it a lot, I recommend it semi frequently to people who are looking for a new career, and basically every dispatch center in the country is always a little short staffed and almost always hiring, so there's plenty of opportunities for it. And usually the requirements are pretty minimal - clean background check, high school or GED, basic computer literacy, good typing skills, ability to speak clearly, etc.
