Nlc to go on strike if needs are not met before may 1st 2017

I think there may be some confusion here.

The National Labor Relations Commission (NLC) is not a labor union that can go on strike. The NLC is an independent agency of the United States government responsible for protecting the rights of employees to form and join labor unions, and to engage in collective bargaining.

If you are referring to a specific labor union or organization, could you please provide more context or information about which one you are talking about? I'd be happy to try and help you find the information you're looking for.

Additionally, I should note that May 1st, 2017 has already passed, so it's unlikely that any strike would have occurred on that date.
