Tech is a tough nut to crack, because the platform economy, social media, and techno-utopian ideology has shaped much of the software industry into a kind of self-styled professional managerial class, its workers generally apathetic and often staunchly antagonistic to addressing structural issues.
Nevertheless, as software is a labor intensive industry, worker cooperatives may be formed relatively easily in principle, and many are being formed.
Software may be an industry that emerges comparatively early with strong representation by worker-controlled enterprise, without necessarily benefiting so directly from unions.
