Mostly it isn’t unless it is one of those jobs that isn’t needed most of the time but sometimes like for example a soldier or rural fire service and some bean counter thinks yeah we can slash that.

Getting rid of the job gets rid of the people with experience, so it can be a one way switch.

Normally solving a problem with a robot creates more jobs. There are speed cameras, but still you have hidden manually operated speed traps and it frees up resources for drug and alcohol testing.
