Close multiple goroutine if an error occurs in one in go

Question

consider this function :

func doAllWork() error {

    var wg sync.WaitGroup

    for i := 0; i < 2; i++ {

        wg.add(1)
        go func() {

            defer wg.Done()
            for j := 0; j < 10; j++ {
                result, err := work(j)
                if err != nil {
                    // can't use `return err` here
                    // what sould I put instead ? 
                    os.Exit(0)
                }
            }
        }()
    }
    wg.Wait()

    return nil
}

In each goroutine, the function work() is called 10 times. If one call to work() returns an error in any of the running goroutines, I want all the goroutines to stop immediately, and the program to exit. Is it ok to use os.Exit() here ? How should I handle this ?

Edit: this question is different from how to stop a goroutine as here I need to close all goroutines if an error occurs in one
