For Luis Mayusa Prada, death was unceremonious.
While walking to his clothes shop at 8 am on August 8 this year in the heavily militarised Colombian town of Saravena, two men shot him 17 times.
As the men fled on a motorcycle, they left behind a widow and five fatherless children.
Prada became the third member of his family to be assassinated.
Yet the murder of this 43-year-old was not an act of retribution over a business disagreement or over a family dispute. Prada was killed - by men believed to be a right-wing paramilitary - for being a trade union leader.
Deadly profession
Like most of his family, Prada had previously received death threats and moved around the country for decades.
And the case highlights the danger of trade unionist membership in Colombia.
At least 27 trade unionists have been killed this year and almost 3,000 union members are said to have been killed in the past 22 years.
In 97 per cent of cases, no-one has been convicted over the killings.
Carmen Mayusa, Prada's sister, told Al Jazeera: "I'm scared. There's a link between the paramilitaries and the government - a permission to do all of this."
As a nurse and leader of the National Association of Hospital and Clinic Workers (ANTHOC), threats to her own life first forced her to flee her home in the department of Meta in central Colombia with her husband and three children in 1988.
In 2006 she was imprisoned in Bogota, the capital, for 25 days on charges of "rebellion".
Mayusa said that police arrested her and planted a uniform of the rebel Revolutionary Armed Forces of Colombia (Farc) in her home.
Although acquitted in court, she has been prevented from working for over two years due to an appeal against the ruling by the general attorney's office.
But despite this and continued threats against her and her family, Mayusa still has "total involvement" in her union.
'Terrorism' claims
In recent years members of the government, including Francisco Santos, the Colombian vice-president, have publicly denounced trade union members and linked them to "terrorism".
But Mayusa says: "I don't have any links to Farc or armed groups.
"We have been against the government because they have been privatising the hospitals.
"We have been killed for criticising government policy and the people in the position to do something - president [Alvaro] Uribe and his government - don't say anything."
Deaths, insecurity and the stigma now associated with trade unionism in Colombia have reduced their members from more than three million 15 years ago to less than 800,000 today.
Their membership has also been hit by extensive privatisation of Colombian firms by the goverment, and the growing number of foreign companies accessing Colombia's natural resources, some of whom oppose trade union membership for their workers.
Foreign direct investment in Colombia increased nearly five-fold to 33 per cent of national earnings from 1990 up to 2006, and increased by another 30 per cent gross last year.
Free trade controversy
Uribe's government is also advocating a free trade agreement (FTA) with the US.
The FTA would immediately eliminate duties on 80 per cent of US consumer and industrial products, with all duties being removed within 10 years.
Requirements to work with local staff and firms would be removed and protection for patents would be increased, negating opportunities for the local manufacture of cheap goods.
The FTA was first negotiated two years ago, but the Democrats put the pact on hold when they took control of the US congress in November 2006.
The party wants the deal to contain tougher labour standards and has its own concerns about the treatment of trade unions.
Losing out
Cesar Ferrari, professor of economics at the University of Javeriana in Bogota, told Al Jazeera, it was doubtful that the signing of the FTA will be of benefit to workers in the country as it would be hard to see what products could compete against heavily subsidised US goods.
"The consumer will benefit because prices will decrease. But the producers, usually small poor farmers, will lose out," he said.
"And that is a very hard situation for a countryside where there is a lot of unrest."
Ferrari said that the pact instead is effectively providing US support to Colombia's war on drugs in return for political influence and preferential access to the Andean country's market.
The US was "going through Latin American countries one-by-one, making them their own market," Ferrari said.
US aid
Colombia has received about $5.5 billion in aid since 2000 from the US.
Critics say the US assistance augments military operations which often hurt civilians, but the Colombian government says it merely provides funds for its anti-narcotic operations against cocaine producers, who are responsible for 90 per cent of the world's production.
The US maintains its position as Colombia's primary trading partner by a considerable margin and provides the South American country with 26.8 per cent of its imports and receives 35.8 per cent of its exports.
Renan Vega Cantor, a professor of history and economics at the University of Pedagojica, warns that the agreement's conditions will help to further crush the development of trade unions and publicly-owned companies.
"International trade and commerce are demanding better conditions for themselves, meaning that the chances workers have to form trade unions are going to be restricted even more," he said.
Trade 'handicap'
But Angela Maria Orozco, a former Colombian minister of trade who now runs a consultancy on international trade, says that not having a free trade agreement with the US is a handicap in a competitive market.
She also said the role of multinational firms in Colombia was very positive, especially in bringing better working practices and finance where it would otherwise be lacking.
In the short-term Orozco sees only a change occurring for consumers but in the long-term if investment and Colombian competitiveness improve then "a lot of things might get better".
"US-Colombian trade is complimentary, not competitive, so I don't think we will be replaced by anything, except some parts of the agricultural sector," she said.
However, she cautions that the government needs to provide regulations for firms so that they cannot simply "come and abuse" the market.
"This is where the government has a huge responsibility. But [regulations] are still new ideas in Latin America. We are not yet the European Union or US."
Multi-national malpractice
However, concerns remain after a series of high-profile companies were linked to paramilitary groups.
In 2007, Chiquita Brands International, a fruit firm, paid out $25 million in fines to the US government for making payments of more than $1.7 million, primarily to the United Self-Defence Forces of Colombia (AUC), a right-wing paramilitary group, and the Farc rebel fighters, amongst others.
The Sinaltrainal union has also filed lawsuits against Nestle and Coca-Cola, accusing the companies of being responsible for the deaths of union members.
Additionally, the once semi-secret connections between the paramilitaries, big business and the political establishment have been exposed in evidence given by former fighters in court cases.
"There are tight relations between the government, paramilitaries and corporations," Cantor says.
"The industrialists, commerce, landowners and TNCs [Transnational Corportations] were all behind the paramilitary groups."
He also says that the policies of the government towards the unions are an attempt to remove any opposition to pro-free-market goals that benefit Colombia's elite.
Plight of poor
Colombia's economy has grown 5.6 per cent in the past five years but the benefits have not been felt by all.
The UN says 18 per cent of the country's 44 million population live on less than $2 a day, while in 2006 the richest 10 per cent of Colombia's population lived on nearly 47 per cent of the country's income.
And this has not gone unnoticed by many Colombians.
As Mayusa says: "For us there has been no benefits for the poor even though there could be.
"They are still suffering, still hungry, without jobs and medical facilities. And even worse they are being killed while the economy grows."
