Hundreds of Transportation Security Administration officers, who are required to work without paychecks through the partial government shutdown, have called out from work this week from at least four major airports.

The mass call outs could inevitably mean air travel is less secure, especially as the shutdown enters its second week with no clear end to the political stalemate in sight.

“This will definitely affect the flying public who we are sworn to protect,” said Hydrick Thomas, president of the national TSA employee union.

In the more than two full weeks of a partial government shutdown, the fallout of major agencies screeching to a halt has had a disparate impact on the public, hitting mostly low-wage federal workers who are either furloughed or working without pay.

Aside from closures at public institutions and parks, most everyday Americans have been shielded from the effects.

Congress needs to push through seven new spending bills in order to turn the lights back on at the roughly quarter of the federal government that remains unfunded.

The sticking point is funding for the Department of Homeland Security, which holds the pursestrings to funds over border security.

So far, President Trump has refused to step away from his $5 billion border wall; congressional Democrats have meanwhile capped their border security offer to $1.3 billion.

But the longer the shutdown continues to drag on, the more programs that intersect with the public could be affected.

Already, stories are emerging of people seeing delays for everything from receiving their tax returns, to some farmers counting on federal loans to see them through the trade war with China.

Amazingly, the Trump administration did not anticipate the full scale of a long-term shutdown.

It was only this week that top officials within the administration realized the full scale of how a protracted shutdown might play out, the Washington Post reports.

Agency heads are now reportedly exploring their options to intervene if new funding is not delivered.

One more week, and the US could pass the threshold for the longest government shutdown in history.

Federal officials are now coming up with contingency plans to ward off the ill-effects of funding gaps.

Around 420,000 federal employees are working on the expectation they’ll receive back-pay, as they have during previous shutdowns.

They’ll really start to see the full weight of the shutdown on January 11, their scheduled payday.

Another 380,000 federal workers have been furloughed.
