I have belonged to a union for 19 years and have never seen or done anything illegal. Bad mouth them if you will, but please don't spread lies. For all their faults, Unions are what make the middle class viable in our country.
However, there are those of us who have to work on-site. We don't work in climate controlled offices and bringing our kids to work would be dangerous for them.
Many middle class people work for employers who offer no childcare options, to assume that your fringe benefits are commonplace is a mistake.
