I'll go ahead and say the vast majority of docusign workers are white collar. Other than building maintenance and sales they have no ground game that would require low skill labor.

In my experience, tech companies contract out roles like security, food, janitorial, shipping, and even facilities, so those people would not be included in the 7000-person figure. The people who manage the relationships with the contracting companies are decidedly white-collar.

But maybe DocuSign doesn't do it that way, I don't actually know.
