A strike force is a term used to describe a group of people who are organized and united in order to achieve a common goal. In this case, the term 'strike force' is being used to refer to a UNION, which is an organization of workers who come together to protect their rights and interests in the workplace. The UNION works to ensure that workers are treated fairly and receive fair wages and benefits. By coming together as a unified group, the UNION is able to negotiate with employers and fight for better working conditions.
