“Music teachers who carry out the work of the foundation established by the violinist Midori went on strike on Thursday, denouncing what they said were a lack of raises, unfair pay and attempts to limit pensions.” Teachers in the program are paid $40 an hour, but say they are given only a few hours of work per week and are asked to travel for hours between classes. “The foundation countered that the teachers were making unreasonable demands on an organization created to do good.”
