Reporting Highlights
- Shortage of Skilled Workers: Many blame immigrants for taking American jobs, but some trades face serious shortages — the U.S. needs 300,000 more welders — and immigrants have helped fill the gap.
- Backlog in Navy Ships: The lack of skilled workers has meant that even defense industries, such as Navy shipbuilding, can’t find enough qualified workers and can’t build fast enough.
- Undocumented, Unprotected: The undocumented workers who step in tend to be contractors, not employees, leaving them with fewer protections when things go wrong.
These highlights were written by the reporters and editors who worked on this story.
On the morning of Jan. 22, 2024, Elmer De León Pérez descended deep into the bowels of a ship that he was helping to build in Houma, Louisiana. Pérez was a welder, working to construct one of the U.S. government’s most sophisticated ships, an $89 million vessel for tracking hurricanes and conducting oceanographic research. It was funded by President Joe Biden’s signature climate legislation.
Pérez’s assignment had him working at the bottom of a nearly 12-foot ballast tank, according to a subsequent police report; the walls were just 4 feet apart. That meant standing inside a metal cylinder, roughly twice the size of a household water heater, using an argon-gas torch whose flame can burn as hot as 20,000 degrees.
Something went very wrong that day. In the afternoon, workers noticed that Pérez, 20, had not come up for lunch. Friends and family began calling, with no answer.
His coworkers found him slumped over in the tank. “I couldn’t get to him because the gas was too strong,” one of them told ProPublica. “I started screaming, ‘Help! Help! Help!’”
When emergency workers found his body, Pérez was already showing signs of rigor mortis. A coroner’s report would note that he was wearing a red hoodie, plaid pajama pants and brown steel-toed boots, and that a “copious amount of clear fluid was noted to the mouth and nose,” as well as on the sleeve of his shirt. The coroner concluded that Pérez “died as a result of bilateral severe pulmonary consolidation and edema” — fluid in the lungs — and “copper and nickel intoxication.” (The ship, like many, used copper-nickel alloys as a coating because they resist corrosion from salt water.)
Pérez had worked for roughly the previous two years at the shipyard, which is owned by Thoma-Sea, a large employer with hundreds of millions of dollars in federal defense contracts. If employees are hurt or killed at work, they and their families are eligible for significant financial help. If one dies in an accident, for example, federal law requires companies such as Thoma-Sea to pay any surviving children. For an employee who perished the way Pérez did,
