go - "undefined" function declared in another file?

Question

I'm trying to write a basic go program that calls a function on a different file, but a part of the same package. However, it returns:

undefined: NewEmployee

Here is the source code:

main.go:

package main

func main() {
emp := NewEmployee()    
}

employee.go:

package main

type Employee struct {
    name string
    age int
}   

func NewEmployee() *Employee {
    p := &Employee{}
    return p
}

func PrintEmployee (p *Employee)  {
    return "Hello world!"
}
