DUBAI, United Arab Emirates (AP) — An annual midday work ban goes into effect this month across much of the Arabian Peninsula to protect construction workers and outdoor laborers from the risks of direct sunlight and extremely high temperatures during the hottest summer months.

The ban, which stands out as one of the most strictly enforced laws aimed at protecting migrant workers in Gulf Arab countries, sheds light on the often difficult working conditions for millions of expatriate laborers who make up the bulk of the workforce here. They provide the manpower to build high-rises, shopping malls, highways and other mega-construction projects sweeping through the region.
