Getting the job, yes (if there's any available). Keeping the job, maybe.

Service dispatcher is tough because you have to deal with customers and finicky technicians. No one wants to make your job easy and in fact feels like they are trying to sabotage you.

Trucking dispatcher is mostly automated in large businesses. Meaning a single person manages a whole warehouse or distribution center, and everyone else is just stocking shelfs or loading trucks.

For the local deliveries there's two kinds, the regular scheduled (planned) deliveries and the parcel type like amazon delivery. The oncall parcel type is the most stressful and has the highest turnover. It's usually subcontracted out so there's very little stability.

Long haul deliveries is planned long in advance has lots of built in automation and requires someone that can plan far in advance and be willing to make decisions that can bankrupt companies because orders are lost or didn't make it on time. They have strict schedules and operating procedures. So they are stressful jobs because a single mistake can be devastating but you are usually a cog in the machine so as long as you do your job, you should be fine.
