As a manual labor occupation, to attract free workers the wages paid to laborers are higher than those paid in general to other types of unskilled workers (see
dirty, dangerous and demeaning). In the United States, a union laborer earns equal or greater than most work available to anyone with a bachelor's degree. This is one of a few fields where someone without a high school diploma can still earn a
living wage. Union, heavy construction and highway construction laborers earn on average (2008 US) $25.47/h compared to 13.72/h for non-union laborers. In addition to paid earnings, union laborers enjoy the benefits of medical insurance, vacation pay, pension plans, representation and vocational schools; totaling $45/hr (2012 US) and some with special skills earn 'over-rate' wages. It is not uncommon for young
civil engineers,
construction managers and
construction engineers typical salary of (2007 US$) 40,000 to 60,000 to fall short of their union laborers average wages of 50,000 to 80,000. However, unlike engineers, laborers are not usually employed full-time year-round and face significant hazards. The additional pay laborers receive is often balanced out by the lesser unemployment checks they receive while out of work and the disability checks they receive while injured—often debilitated for life. That is if unemployment and injury insurance is provided, which is often not the case unless they are labor union members. Engineers are also not immune to being out of work. In heavy civil work, some are employed on a project basis and mental injuries due to stress are a different but debilitating hazard. Because of the wide range of skills and ability to simply provide muscle, laborers often earn side-work as independent contractors and
under-the-table work. In construction, the pay for laborers is low enough that planning problems can be solved by "throwing laborers at it." This can become a toxic and dangerous brew of unplanned work that slides forward on the blood and sweat of hard-working laborers—injury rates often soar. The value of work put in place by laborers and the value of avoided rework and increased efficiencies produced by the engineers' planning is a balance of resource utilization on any large project. ==Hazards and conditions==
