Which aspect is essential for improving union membership?

Community engagement is essential for improving union membership because it helps build strong connections between the union and the community it serves. When unions engage with community members, they create awareness about their mission, values, and the benefits of union membership. This engagement can foster solidarity and support for workers' rights by actively involving the community in discussions around labor issues.

Moreover, a union that is actively involved in community activities can better address the needs and concerns of both its members and the surrounding population. This can lead to an increased sense of belonging and higher participation rates among workers, ultimately strengthening the union's overall presence and influence.

Engaging with the community can also help counteract negative perceptions about unions and demonstrate their positive impact on social justice and economic equity. When unions effectively communicate their successes and advocate for workers, they can inspire more individuals to join and support the movement.

The other options, such as mass layoffs, high-profile strikes, and increased corporate profits, do not inherently promote union membership. In fact, mass layoffs can lead to job insecurity and decreased interest in union participation, high-profile strikes may not appeal to all potential members and can sometimes create divisions, and increased corporate profits often do not directly correlate with the benefits or significance of union membership.
