I wouldn't say that working efficiently with people directly counts as "meta". Productive cooperation with others sounds like a straightforward skill to improve, with no new rules being introduced. Maybe new company/team organizational approaches or methodologies (Waterfall, Kanban, etc.) can count as playing the meta and give you an edge over the competition.
