(CNN) -- The bad news came via certified letter to Norma Jimenez, Edna Rodriguez and nearly 17,000 other Puerto Ricans this month.



Thousands last week protest government layoffs in Puerto Rico.



To cut spending, Puerto Rico announced last month that thousands of government employees would be fired in the second round of layoffs this year. More than 7,800 public employees were fired in March.



"I was fearful because of the uncertainty," Jimenez, 42, an auxiliary administrator for the U.S. territory's Department of Education told CNN. "Will the letter come or not come?"



The letter came, and it said that under a measure authorized by an emergency fiscal bill, her last day of work would be January 8 of next year.



Rodriguez, who worked for the education department for 11 years as a receptionist, got the same letter, but with a November 6 termination date.



"It was as if the world collapsed," she told CNN.



And presumably, so it goes for the thousands of other public employees who were laid off.



The austere measures are a bid by the government to stabilize a fiscal mess and save Puerto Rico's credit rating. According to government figures, the U.S. territory faces a $3.2 billion budget deficit -- proportionally, the largest shortfall in the United States -- and is entering a fourth year of recession.



The severity of the plan reflects the aftermath of what experts say is years, maybe decades, of the lack of a forward-looking economic policy.



Confronted with the fear that the credit-rating agencies might reduce Puerto Rico's rating to junk status, the administration of Gov. Luis Fortuno has taken strong, but controversial, steps.



"Every layoff letter has a name, and every name has a story," Puerto Rico Secretary of State Kenneth McClintock said in an interview with CNN.



But, he said, "Doing nothing was not an alternative."



The governor and other officials cut their salaries and trimmed spending in other areas, but the massive layoffs were necessary to avert the downgraded credit rating, McClintock said.



"If that happened, we would become the first state in the history of the U.S. to have its credit downgraded to junk bond," he said.



Puerto Rico's unemployment rate is nearly 16 percent, according to the U.S. Bureau of Labor Statistics.



According to government calculations, a downgraded credit rating would have pushed that figure toward 25 percent unemployment, McClintock said.



The government is betting that the reduced spending, combined with $6.5 billion in combined federal and local stimulus funds, will be enough to get the territory back on solid footing. As a U.S. commonwealth, Puerto Rico exercises much autonomy, but still falls under U.S. jurisdiction. In addition to the federal stimulus money, Puerto Rican officials traveled to Washington last month to lobby for discretionary stimulus grants.



How did Puerto Rico get into this predicament?



"This did not happen overnight," said Miguel Soto-Class, executive director of the Center for the New Economy, an independent think tank in Puerto Rico.



For too long, the island has been dependent on a single industry at a time, Soto-Class told CNN.



First it was coffee, then sugar, and most recently pharmaceutical production plants.



Under the terms of a special tax break, U.S. companies were exempt from paying federal income tax on profits earned by their Puerto Rican manufacturing subsidiaries. This brought plenty of companies and jobs to the island until Congress voted to phase out the benefits between 1996 and 2006.



When a number of foreign companies began to pull back, Puerto Rico saw that the local economy had not absorbed many benefits from the foreign plants, Soto-Class said. For instance, local restaurants didn't sprout near the plants because food was usually done in-house. Likewise, the foreign companies used their own accountants, leaving local CPAs few opportunities to grow.



"That wasn't the cause, but it laid bare that we hadn't had an economic development model in a long time," Soto-Class said.
