Job offer and demand

Offer and labor demand of my country Colombia.
To describe the supply and demand of my city it is better to speak a little more general and introduce the entire department of La Guajira.
Riohacha was classified as a tourist district. A small part of the income of citizens is based on tourism, as they are:
• The sale of meals, formal and informal
• hotel and excursion packages.
• Sales of typical crafts of the department (wayuu)
• Bars and discotheques
In addition to the tourist market, the inhabitants of the department have two large companies that are: Cerrejón, Ecopetrol and Corpoguajira. Cerrojon is one of the largest natural coal mining companies in the department and mostly contracted to a large part of the people in the department. Corpoguajira is an entity that is based on environmental improvement and management project and Ecopetrol is an oil extraction company.
Other sources of work in my city are companies in small sectors, such as shops, some foundations, hospitals and EPS, educational institutions, public transport, etc. Which are also common in any city.

Labor laws

What would you change about labor policies in your city?
In my country Colombia and in my city Riohacha in the department of La Guajira. There are relatively new forms of labor contract, which as more than providing progress to the working population benefits the empowered business that as though it is not a bad thing, it is too unfair for the majority of the working class. As are the quarterly renewable fixed term contracts, which leaves the worker out of some bonus benefits, bonuses, vacations and others.
Also, contracts for the provision of services, which excludes workers from liquidation at the end of the contract, also excludes them from care for occupational hazards, health and pension, who are mostly assumed by the workers themselves and not by the company. Another type of norm that although it is not legal is very usual in our country is not to contract people over 35 who consider themselves an old person, denying the  to a person to work.
