Final answer:
Educators are the public-sector employee group most likely to participate in strikes, with unions like NEA and AFT frequently organizing such actions.
Step-by-step explanation:
The public-sector employee group most likely to participate in strikes is educators. This is evidenced by the presence of large and influential unions representing teachers and educators across the country, such as the National Education Association (NEA) and the American Federation of Teachers (AFT). These organizations have a history of organizing their members to engage in strikes for better working conditions, salaries, and benefits. Additionally, while many states deem it illegal for certain public-sector workers like police officers to strike, educators have been part of significant work stoppages and strikes.
It is also important to note the broader context of organized labor in the United States. Unions became a legal way for workers to organize during the Great Depression. Although over time, the manufacturing sector, where unions were traditionally strong, has declined. Service industries, which include government employees, have grown, and the biggest unions in these sectors represent government workers such as educators and service employees.
