"Laboring the point" means "dealing with an issue or argument excessively, in terms of both time and detail".
Since the article itself talks about the opposite opinions (points) of bringing in "unskilled workders", and in "providing baby bonus", and "labor" can mean "unskilled workers", "difficult despite working hard", as well as "the painful process of giving birth (to babies)", I believe the author chose the expression "laboring the point" to mean "too much talking about unskilled workers and baby bonus won't solve the problem, but will only make the process more painful and difficult".
