EmpLoymEnT, work, And HEALTH inEquALiTiES - a global perspective<br />

firms, most of which are home-based or family-owned enterprises. In<br />

this case, workers are mostly family members or relatives, and the<br />

overlap of capital and labour functions are common (Portes et al., 1989;<br />

Daza, 2005). The major problem is that this lack of statutory regulation<br />

means that there is no way to ensure the protection of working<br />

conditions, wages, or acceptable levels of occupational health and safety.<br />

Workers having informal jobs are disadvantaged compared to<br />

formally-hired workers in several aspects that separately or<br />

together affect their health and safety. The most important factor is<br />

poverty, since several studies show that firms in the informal<br />

economy usually have <strong>low</strong> profits and informal workers have <strong>low</strong>er<br />

salaries than those in formal firms. Wages are a large component of<br />

family income and therefore the informal jobs are important<br />

determinants of consumption patterns. Small business owners, on<br />

the other hand, do not fare worse than their formal counterparts.<br />

also, informal employment affects the family, as children of women<br />

working as street vendors who accompanied their mothers,<br />

compared to the general population, have an increased prevalence<br />

of acute diseases (38.0% vs. 27.3%) and injuries (5.8% vs. 3.6%).<br />

Since firms in the informal economy are unregistered and out of state<br />

control, working conditions, which are largely dependent on the<br />

reinforcement of workers’ health and safety laws and regulation by the<br />

state, are worse than in formal firms. large formal enterprises may keep<br />

part of their workers illegally unregistered, with only a verbal<br />

employment arrangement. Formal firms may keep informallyemployed<br />

individuals in the most dangerous activities in order to<br />

avoid fines resulting from occupational injuries or diseases, or to<br />

reduce expenses from labour-related taxes, to have more flexibility<br />

for hiring and firing, or keep payments under the legal minimum<br />

wages (IlO, 2006). Occupational hazards are common. For instance,<br />

awkward postures and exposure to toxic chemicals, excessive<br />

noise, poor sanitation, high workload, pesticides, violence and<br />

push-bicycle in the streets of Hue (Vietnam). sexual assault (Iriart et al., 2006) are commonly observed in<br />

informal economy settings. as a result, a high proportion of<br />

occupational injuries and diseases among informal workers have been<br />

reported in several studies. Informal workers reported receiving less<br />

training and supervision than formal workers and limited access to<br />

protective equipment. Other factors associated with the informal<br />

economy and informal jobs are a <strong>low</strong> standard of housing and sanitation<br />

and inappropriate management of waste or toxic substances that can<br />

affect the environment and health. The scientific literature on<br />

occupational health and the informal economy is scarce and most studies<br />

are descriptive, a fact which limits the generalisation of results (Da Silva,<br />
