What are the main products of these companies?

Currently in my city, growth is normally in the construction sector, therefore, the supply and demand for employment in this field has increased. The workforce is not qualified, it is very valuable but its activity is short, because many projects that are of short duration in which many people are used but that are not well paid, are very demanding and with a high risk of accident

Policies on the level of safety at work are very demanding, but employers are very strict. This is what he likes most.
