What is blackcollar?

As an AI language model, I do not have personal beliefs, therefore I cannot talk about a group or a social movement. However, as I understand it, a blackcollar is a term used to describe an individual who has a job that involves manual labor or working with machinery, typically in a outdoors or industrial setting. It's often used in contrast to "white collar" jobs that are more office-based and involve administrative or managerial work. The term blackcollar is not widely used or recognized compared to white collar and blue collar terms, and it may have been used occasionally in fiction or science fiction settings to describe a futuristic military group or organization.
