Guam mirrors the federal tax code. We are subject to federal law. We pay federal tax same as anyone and we still can’t vote for president. Anyway the flsa applies here if that’s not enough majority of it is written into local law. If under flsa you can collect double your unpaid wages if under Guam law you can collect triple.

From what I’ve read you do not pay US federal tax
From guamtax.com
The U.S. Congress created the Territorial Government of Guam as a separate taxing jurisdiction by enactment of the Organic Act of Guam in 1950. Section 31 of the Act provides that the income tax laws in force in the United States shall be the income tax laws of Guam, substituting Guam for the United States where necessary and omitting any inapplicable or incompatible provisions. The U.S. Internal Revenue Code with such changes constitutes the Guam Territorial Income Tax Law.
This is from irs.gov
If you are a bona fide resident of Guam during the entire tax year, file your return with Guam. This applies to all bona fide residents who are citizens, resident aliens, or nonresident aliens of the United States.
You do not file your tax return with the US Federal IRS
While the laws are copies of the US tax laws, the use of Guam replaces United States. The irs code has been similarly altered.
You have also proven the US FLSA doesn’t apply. If in Guam you can collect treble damages where the US FLSA demands double damages, that alone proves it is not the same law.
But if you want to argue the US FLSA applies:
There are no federal laws requiring lunch breaks or any breaks for most workers. Due to that you wouldn’t be due anything for not being afforded lunches or breaks. Any break laws are for specific jobs such as truck drivers and train engineers as well as a few other very specific occupations.
If applying US law, you wouldn’t be due anything other then your contracted pay. To be able to make any other claim you would have to have your work ruled that you are an employee. You can think you are due the moon and the stars but until somebody in an authoritative position rules that you are an employee, you aren’t due anything.
