Public sector unions are organizations that represent employees working in government jobs, such as those in education, healthcare, and public safety. These unions advocate for workers' rights, negotiate contracts, and help secure better wages, benefits, and working conditions for their members. These unions play a crucial role in ensuring that public sector employees have a collective voice in discussions with government employers. By organizing workers, public sector unions aim to improve job security and promote fair treatment in the workplace, ultimately benefiting both employees and the communities they serve.
