UNION TOWNSHIP — Theodore Jakubowski has seen this before. The 64-year-old man saw it as a child growing up in Union Township, as Italian, Irish and Polish families came to his community in droves after World War II and learned to live together despite their differences. And now things are changing again in Union, and in few places in New Jersey is that change happening as quickly or as completely as it is here in this town of 56,600.
