Although it's illegal to fire workers for attempting to organize, it's a common tactic because it's hard to prove the reason for a worker's dismissal. Either workers can file a complaint with the National Labor Relations Board, which could take months to resolve, or a union can try to settle the matter directly with the company on the workers' behalf. In this case, union 32BJ did both and was able to get the workers their jobs back without the National Labor Relations Board. 32BJ is now in talks with Impark about a "fair process" to start a union.
