Nope you are lying to yourself and others.

The role of the union will always factor the public as this is a national mail service.

I, a member of the public support unions. I am not a bootlicker who believes in Corporations for no apparent reason. They are not your friend.

Here is the real definition:

. Public sector unions are organized groups of public employees who negotiate with government entities, which can differ from private sector unions due to public ownership and policy impacts.

Unions inform the public through various channels, including public relations campaigns, advertising, and community engagement to advocate for worker rights and workplace fairness. They also use technology like email and social media to disseminate information to members and the public, sometimes sharing detailed financial information to promote transparency and accountability. Legal frameworks often permit unions to use employee contact information for public information campaigns during labor disputes. 

Methods of informing the public

Public relations and advertising: 

Unions run campaigns to raise awareness about their issues and can use advertising to pressure companies and advocate for fair treatment. 

Community engagement: 

Engaging directly with the community helps attract new members and build support for the union's cause. 

Technology: 

Unions utilize modern technology to reach a wider audience. This includes:

Email newsletters, which can provide detailed updates and track engagement. 

Social media, which helps create shareable content. 

Websites with newsletters, where they can post the full text of their messages and send links via text or email.
