New York University's graduate teaching assistants plan next week to strike in order to win back union representation they lost in August. Following a policy reversal by the National Labor Relations Board, NYU decided not to renew the union arrangement earlier this year. NYU said that it was too early to say how many classes would be affected, and that it hoped any disruption would be minimal.
