When I hear that critical lines were cut, I thought to myself "I bet there just happens to be some sort of labor dispute going on with the union guys in California." Sure enough, you guys confirmed it.
My father worked for Verizon (formerly Bell Atlantic, etc) for roughly 15 years until he recently retired. He was "management." EVERY SINGLE TIME the union guys went out on strike, the vandalism began. There's a lot of political back-scratching going on when this happens and the union is VERY good at protecting these guys from any sort of prosecution. Fortunately, one time, one or two guys were electrocuted in Brooklyn (or maybe it was Staten Island) the last time around. They were climbing a pole attempting to cut lines. They successfully sabotaged lines in Fairfield County back in 98 or 99. They set fires in buildings, flooded tunnels containing copper and fiber lines, attack managers physically or damage their cars while they are working and these guys are "picketing." Disgusting behavior.
Union workers are a pathetic bunch. Very petty, very childish, very ignorant and are often despicable. You cut phone lines that people rely on for 911 services because you want a f***ing pay raise??? I hope one day a family member of a union telco worker dies due to an intentionally cut line. Maybe they will learn. but I doubt it.
