A construction worker is someone who is employed as part of a construction crew and will perform many tasks that often involve physical labor on construction sites. However, there are plenty of roles that don't involve being on a construction site. They are responsible for a number of on-site tasks, such as removing debris, erecting scaffolding, loading and unloading building materials, and assisting with operating heavy equipment. 

Construction workers also play a crucial role in ensuring safety protocols are followed on the job site and may be involved in project planning and management. Additionally, they may be required to have specialized skills such as electrical or plumbing expertise.

These roles can also include administrative tasks such as scheduling and budgeting, as well as project management and overseeing the work of subcontractors. Additionally, some construction workers may specialize in areas such as plumbing, electrical work, or carpentry.
