Having personally been in three different private sector unions, I would say that this is true. I am extremely critical of them, would not join one again and would change careers if my field significantly unionized. I've posted at length about this before. In the private sector, collective bargaining leads to worse outcomes both for employees and for consumers. Public sector unions (see federal employment) are an entirely different animal and generally have been very effective.
