Migrated in from https://www.w3.org/2011/webschema/track/issues/17
http://schema.org/Organization has various subtypes including Corporation etc, but doesn't cover Labo[u]r Union.
Raised by Kendall Clark, https://twitter.com/kendall/status/210422142620286976
The schema has the following subtypes currently: Corporation, EducationalOrganization, GovernmentOrganization, LocalBusiness, NGO, PerformingGroup, SportsTeam
The British English variant of this concept is http://en.wikipedia.org/wiki/Trade_union
Generally Schema.org uses US English, but if a more neutral term / spelling is available, that helps.
(there's a draft proposal around somewhere in RDFa/RDFS too)
Earlier proposal was:
<div typeof="rdfs:Class" resource="http://schema.org/WorkersUnion">
<span class="h" property="rdfs:label">WorkersUnion</span>
<span property="rdfs:comment">A Workers Union (also known as a Labor Union, Labour Union, or Trade Union) is an organization that promotes the interests of its worker members by collectively bargaining with management, organizing, and political lobbying.</span>
<span>Subclass of: <a property="rdfs:subClassOf" href="http://schema.org/Organization">Organization</a></span>
<span>Source: <a property="dc:source" href="http://www.w3.org/wiki/WebSchemas/SchemaDotOrgSources#source_WorkersUnionClass">WebSchemas community</a></span>
Added WorkersUnion to pending.schema.org
Original discussion from 2013(!)
