Here's who was working with no pay through the shutdown

(CNN) The difficulties facing government employees forced to work without pay during the shutdown didn't simply disappear when President Donald Trump reopened the government for three weeks on Friday.

Many of these approximately 450,000 federal employees were forced to pull from savings or find other ways to stretch their dollars as the shutdown stretched on for 35 days. Now, they must still wait for their back pay to arrive and wait to see the extended effects of those missed paychecks.

Despite the battle on Capitol Hill, federal employees nationwide continued to do their jobs. Here are some of the stories of those who had to work during the longest government shutdown in US history:

Department of Homeland Security

Transportation Security Administration

• Hundreds of TSA officers, who were required to work without paychecks through the partial government shutdown, called out from work from at least four major airports.

• TSA officials in more than 10 states with more than 100 airports received an email asking for 250 employees to move from their home airports to those airports struggling with low staffing.
• This family thought their troubles were over. Jessica Caraballo, a Transportation Security Administration officer at Atlanta's Hartsfield-Jackson International Airport, had just been promoted to a full-time position and her husband got a new job selling cars. Then the government shutdown left them in limbo.
• This week, some TSA agents at Hawaii airports started to resign, Hawaii News Now reported. The newspaper reported at least one screener lived out of their car at the airport during the work week and would travel home only once a week to save gas.

Schultz, the branch's top official, wrote in a statement.
• About 41,000 active-duty Coast Guardsmen who were working without pay and were unsure when they'd see their next paychecks were told they should consider having garage sales, babysitting, and dog-walking, the Washington Post reported.

• "Nearly 90 percent of DHS employees are currently working on essential national security projects and programs without a paycheck," DHS spokesman Tyler Houlton told CNN in a statement.

Secret Service

• More than 6,000 Secret Service Agents worked during the shutdown to protect the current and former presidents and their families. "If you've got guys thinking about how they're going to make their house payment, I can just tell you, you're not doing your job right. Your head is not in the right place -- this is affecting people," one agent told CNN.
• Former president George W. Bush got pizza for his Secret Service details and called for an end to the shutdown. "It's time for leaders on both sides to put politics aside, come together, and end this shutdown," he wrote on Instagram.
• Special shutdown challenge coins were being distributed among US Secret Service personnel and their families, who are expressing frustration at the requirement they work without pay.

• William Striffler, an air traffic controller working without pay at Newark Liberty International Airport in New Jersey, showed CNN the pay stub for $0.00 he received after working 64 hours during the first pay cycle of the shutdown.
