A father and essential worker died of COVID-19. He was afraid of losing his job.

Alisha Álvarez, 28, said a final goodbye to her father at his funeral service Friday, still wondering if she could have done more to convince him that he didn't have to go to work if he feared contracting coronavirus.

José Roberto Álvarez Mena, her dad, was one of thousands of essential workers who showed up to work as California saw a surge in coronavirus cases after partially reopening its economy earlier this summer. Álvarez Mena was working as the head of maintenance for Mission Foods Corp. in Commerce, California, when he tested positive to COVID-19 on June 28.

Alisha's mother and older sister, both of whom lived with José Roberto, also tested positive for the virus during the same time period. While both women recovered, José Roberto's symptoms worsened. On July 4, he was hospitalized after struggling to breathe.

He was then admitted to the hospital’s intensive care unit on the following day. José Roberto, known to people in his Los Angeles community as "Beto Mena," spent two weeks connected to a respirator until he died on July 20. He was 67.

"It's the most painful thing, especially because you can't see them in person, you can't say bye. People have to remember that, when they say they don't want to wear masks," Alisha told NBC News. "This is not a political issue. This is harming people and ruining their lives."

José Roberto, who was an engineer by profession, emigrated to the United States from El Salvador in the 1980s "to work and provide for his kids," said Alisha, adding that he was the family's sole provider. "That's why work was always the most important thing to him."

"My dad never said no to helping people. He was always there for any family member no matter what. He was the kind of guy who would go into work on his days off because his boss would call him for help," said Alisha.

The Los Angeles Public Health Department ordered the temporary closure of Mission Foods Corp. on July 29 for failing to report a COVID-19 outbreak that sickened at least 40 of their workers; they also closed two other food processors. The company was allowed to reopen its facilities one day later.

County officials were investigating the deaths of two Mission Foods Corp. employees, including José Roberto's, the Los Angeles Times reported.

The family has criticized the company for failing to protect José Roberto. Alisha said their actions were "straight up negligent." One month before Mission Foods' closure, José Roberto told his family he was hearing rumblings at work of people getting sick, according to his daughter.
