What term describes unskilled workers who perform essential tasks on a construction site?

The term "laborers" refers to unskilled workers whose primary role is to perform essential tasks on a construction site. These tasks often include physical labor such as moving materials, cleaning work areas, and assisting skilled tradespeople with their tasks. Laborers play a crucial role in construction projects by ensuring that the site is organized and that materials are readily available for more specialized workers.

While "helpers" can also refer to individuals assisting skilled workers, they may not necessarily be categorized as unskilled, or they might have specific duties that differ from those of laborers. "Apprentices" are typically individuals who are learning a trade under the guidance of a skilled worker and may have some level of training or skill already. "Contract assistants" may refer to workers who are hired on a contract basis, which implies a certain level of skill or specialization, differentiating them from the general classification of unskilled laborers. Therefore, "laborers" is the most accurate term for describing unskilled workers engaged in essential construction site tasks.
