Tensions between Verizon and its striking 45,000 employees increased on Friday as the company called the FBI to investigate allegations of sabotage at some of its network facilities.  The 45,000 Verizon landline workers are members of the Communications Workers of America, representing employees in the Northeast, including New York and Maryland.  In New York City The already short staffed NYPD has placed officers to watch over all Verizon properties after discovering more than 90 acts of sabotage since the strike began including cut wires causing many loss of phone and internet service.   A Communications Workers of America spokeswoman said in an email that the union doesn't support illegal acts. "CWA does not condone illegal action of any kind, and instructs its members to conduct all strike activities in accordance with labor law," CWA communications director Candice Johnson wrote.  CWA also states that despite the company's success it "has never come to the table with offers of vastly increased compensation and benefits for the technicians who make Verizon Wireless' enormous profitability possible." The CWA further state that the contracts for landline workers "were written in the rotary phone era and are no longer applicable.  Our contracts need to be modernized and we need our union members to work with us to make that happen."   The short-staffed department of the NYPD, already stretched thin in all five boroughs is monitoring Verizon garages, electrical plants, communications hubs and most Verizon facility to prevent any further damage. Shouldn't the Verizon corporate supply it's own security?  Why should the citizens of New York City suffer for another greedy corporate giant?
