如何正确防止数据争用？

According to the docs doing the following prevents a data race:

    var wg sync.WaitGroup
    wg.Add(5)
    for i := 0; i < 5; i++ {
        go func(j int) {
            fmt.Println(j) // Good. Read local copy of the loop counter.
            wg.Done()
        }(i)
    }
    wg.Wait()

however if I have code such as:

type Job struct {
    Work []string
}

var Queue chan Job


func work(id string, type int32) {

    job := Job{Work: []string{"A","B","C"}}

    go func(j Job, ty int32) {
        if ty == 1 {
        // do some other task
        }
        Queue <- j
    } (job, type) // RACE ON THIS LINE

    if type == 1 {
        // do something
    }

    return
}

work is being called via. gRPC.

the data race detector tells me that the go routine is producing a data race. I am thinking that there is something I am missing here but can't quite seem to find what that is.
