A district court order was immediately appealable insofar as it prohibited the defendant employer from communicating with workers about this opt-in FLSA action or soliciting them not to join the action, but not insofar as it voided the agreements that the employer had solicited from workers releasing FLSA claims or agreeing not to join the action.  The appealable portion of the order was akin to an injunction.  The non-appealable portion was not.  The ban on communications was justified because the employer’s earlier solicitation efforts had been misleading.
