this has a map of unionized vs RTW states
right to work seems like a good idea up front
but in the end it keeps wages low and only really benefits large corporations and rich people
not surprisingly RTW states seems to follow RED/BLUE state lines (rep/dem)

im based on long island but work the tristate area (lower NY, northern NJ, and western CT)

funny story about a union guy in a RTW state
my buddy is a CWA (Communications Workers of America) telecom installer in NYC and LI 90% of his work is prevailing (36- 60 and hour)
he was subbed out on a installation in NC
they day the install was to begin the ceiling collapsed
as the GC was flippin out cause of the obvious shoddy work the ceiling guys did my buddy walked up and said "thats what you get when you use non-union labor"
the GC flipped again but in the end he knew my buddy was right
you pay the premium for union guys cause "theyll do it right, the 1st time"
