The PROMESA board (http://www.promesacodex.com/oversight-board.html) has decided they had enough with the government delays and financial plans, so they have drafted and are about to implement a new financial plan for the island, the university, Electric company, Water company and several other government agencies.
Needless to say the Governor of Puerto Rico and the 2 chambers of the goverment legislation bodies are not too happy and plan not to implement some of the measures.
This is likely to end up in Federal court and Congress will likely get involved. The board has financial power over all of the government of Puerto Rico, so likely the plan they implemented will become a series of laws or the government will be found in contend of court, which could result in jail time for some members of the government of Puerto Rico.
The Spanish sections of the newspapers are full of news about this.
Government budget has been cut, legislation budget has been cut, vacation days has been cut to 7 days a year, sick leave will be cut to 7 days a year, right to work is being eliminated, lots of government agencies will have layoffs, toll roads are going up by 5 cents a year until 2023, not sure past that point.
The board has said that the more they delay in implementing the laws required, the smaller the government budget is going to be since they have to make up the savings one way or another.
So in summary, the board had it and is playing hardball. See link above for info on the board which in PR people call it the Junta.
