Aconstruction worker is a person employed in the physicalconstruction of thebuilt environment and itsinfrastructure.

By some definitions, construction workers may be engaged inmanual labour as unskilled or semi-skilled workers.[1] These workers begin by attending to general tasks such as digging, cleaning, and unloading equipment. As they gain more experience, they start to specialize in particular areas - for example, roofing, pipefitting, structural work, or carpentry. Over time, some opt to receive certification and undergo formal training to achieve qualifications and promotion.[2] In other words, they may be skilled tradespeople, or they may be supervisory or managerial personnel.
United Kingdom safety legislation has defined construction workers as people "who work for or under the control of a contractor on a construction site."[3] In Canada, this can include people whose work includes ensuring conformance with building codes and regulations and those who supervise other workers.[4]
Most construction workers are primarily described by the specific level and type of work they perform.Laborers comprise a large grouping in most national construction industries. In the United States, for example, in May 2023, construction sector businesses employed just over 7.9 million people, of whom 859,000 were laborers, while 3.7 million were construction trades workers (including 603,000carpenters, 559,000electricians, 385,000plumbers, and 321,000 equipment operators).[5] Like most business sectors, there is also substantialwhite-collar employment in construction - out of 7.9 million US construction business workers, 681,000 were recorded by theUnited States Department of Labor in May 2023 as in 'office and administrative support occupations', 620,000 in 'management occupations' and 480,000 in 'business and financial operations occupations'.[5]
In 2023, the United States reported that, of the total number of construction workers, 27.7% of workers were Hispanic and around 6.2% were women.[6][7] In some economies, there is also substantial self-employment; in the United Kingdom for example, 1.4 million out of 2.25 million construction workers were classified as self-employed in 2023.[8] In the US in 2015, unincorporated self-employment rates were highest for workers in construction and extraction occupations (14.8 percent).[9]
Construction workers cancolloquially be referred to as "hard hat workers" or "hard hats",[10] as they often wearhard hats for safety while working on construction sites.
The construction industry is a high-hazard sector, encompassing alteration and repair. Workers are exposed to various serious hazards, such as falling debris, unguardedmachinery,heavy equipment,electrocutions,silica dust, andasbestos.[11] Thus, construction safety is intended to ensure a safe environment for workers, who are required to be educated on safety at each site.[12] Construction workers must remain vigilant by keeping work areas clear, learning safe lifting techniques, being aware of seasonal hazards, and regularly inspecting all equipment, among other preventive measures.[4]
All companies in the United States require workers to have an OSHA (Occupational Safety and Health Administration) certification to ensure safety on the worksite. In many cases, OSHA inspectors visit worksites to ensure that all safety protocols are in place to protect workers. Employers are also required by law to have an OSHA job safety poster.[13]
Publications have been issued by authorities to train construction workers on safe working, e.g., when usingpower tools.[14] In some places such as Hong Kong it is an offence if the use of power tools (such asdrills) produces excessive dust or noise and causespollution.[15]
In India, the Building and Other Construction Workers Act 1996 regulates the employment and conditions of service of building and other construction workers and provides for safety, health and welfare measures.[16]

In 2008, aHuman Rights Watch report described unsafe and unfair working conditions in China and a failure on the part of the government to enforce labor standards in the construction industry.[17] TheInternational Labour Organization (ILO) estimated that, at the end of 2006, 90% of the 40 million construction workers in China weremigrant workers. Many turned to work after their farming communities collapsed into poverty.[17]
In the United States,illegal immigrant labor is prevalent in the industry. Due to workers' questionable legal status, some employers commit crimes such aswage theft and violation of workplace standards, running little risk of consequences.[18] Similar abuse occurred inQatar during preparations for the2022 FIFA World Cup where workers, mostly from poor countries in the Indian subcontinent, worked in desert conditions for as little as €6.20 a day.[19]
