# UnownedJob

A unit of schedulable work.

## Declaration

```swift
@frozen struct UnownedJob
```

## Overview

Overview Unless you’re implementing a scheduler, you don’t generally interact with jobs directly. An UnownedJob must be eventually run exactly once using runSynchronously(on:). Not doing so is effectively going to leak and “hang” the work that the job represents (e.g. a Task).
