Women and men in the informal economy: a statistical picture ILO

Globally, 15.7 per cent of employees in permanent full-time employment hold informal jobs, i.e. having no employment related social and labour protections. The proportion of employees in informal employment increases significantly among part-time employees (44.0 per cent), and among employees in temporary employment (59.6 per cent) and is highest for employees in “temporary part-time jobs” (64.4 per cent), especially among men (68.1 per cent). Women part time employees are less likely than men to be informal. Just above one-third of women employees working less than 35 hours a week are in informal employment, as compared to 54.2 per cent among men
The proportion of workers in time-related underemployment is higher among workers in informal employment in most countries. Workers in informal employment are even more likely to work excessive hours (more than 48 hours a week or even more than 60 hours a week), especially employees. This phenomenon in Asia and the Pacific is extreme, but working longer hours when holding informal jobs seems to be the reality for half of all employees in the developing and emerging world. This reality is significantly different from the situation of employees in developed countries, as less than 16 per cent work long hours, without any difference between formal or informal employment. Own-account
workers show a different picture, as own-account workers owning formal economic units tend to work longer hours than their counterparts operating informally.
