I think airport workers have not been paid since Irma so they're refusing to work until that is settled.

There were two videos. First I didn't understand at all. Second one had a lady claiming to speak for all and I understood little except "we all have mouths to feed..." Near end of that video a gentleman came forward and spoke to someone off camera and said something like if the people don't get paid they will not work. He said airport will open Thursday but close again if the meeting on Friday is not satisfactory to the workers and stay closed until payments are made.
