SAO PAULO (Reuters) -Metalworkers at Brazilian planemaker Embraer's Sao Jose dos Campos plant on Tuesday decided to suspend a strike they had started earlier in the day as they campaign for higher wages. Local union Sindmetal said in a statement the strike had been called off after about three hours because workers felt "intimidated by the large number of police officers and security guards on site." Sindmetal said it would pitch a new strike with workers on another shift at 3 p.m. local time (1800 GMT).
