For night-shift workers who keep things running while everyone else rests, falling back at 2 a.m. Sunday means a longer shift and, potentially, a little more pay.
"I typically work a 7 p.m. to 7 a.m. shift," said Nicole Robinson, a certified nursing assistant at CHI Memorial Hospital. "That Saturday night shift will be 13 hours. That one extra hour, honestly, you don't even notice it."
Electronic timeclocks are set up to make both the spring-forward and fall-back adjustments seamless for hospital employees, said John Steele, market director of human resources. If hourly employees go over 40 hours in a week, they'll automatically get overtime, he said. But it wasn't always so simple, he added.
"I've been here 25 years, and we had to manually do adjustments before these systems," he said.
The story is similar at the Chattanooga Police Department, where officers working their 10-hour night shifts Saturday into Sunday will end up with 11 hours on the clock — and overtime if they earn it by going over 40 for the week, said Elisa Myzal, spokeswoman for the department.
"The automatic timeclock system will just add an hour to their shifts," she said.
There was a time before electronic timekeeping when that hour just disappeared, and the understanding was that officers would get it back in the spring. But that wasn't a very popular arrangement, she said.
"It used to be just a lost hour," she said.
Chattanooga firefighters work on a salaried basis so there's no hour-counting process for their 24-hour shifts, department spokeswoman Lindsey Rogers said.
The wee-hours time change will also hit local bars that stay open until 2 a.m. or later, but many establishments plan to shut it down when the clock strikes 2 the first time.
"We normally do last call at 1:30 or 1:45 and shut stuff down," said Jason Bowers, owner of the Bitter Alibi. "Most of my staff is like, 'Can we please not stay at work another hour?'"
The bar is also a brunch hotspot, he said, and asking folks to stay another hour at night and then come in and brew coffee and make eggs seems a bit much to ask, he added.
"That's a tough sell," Bowers said. "We have a really busy Sunday morning brunch."
At the Hair of the Dog, they'll also close things down at 2 a.m., said Courtney Wright, the bar's general manager.
"We don't feel like our guests need another hour to drink," he said. "People who are out at that hour, there's no reason to keep them out later."
The Tennessee Alcoholic Beverage Commission does permit bars that stay open until 2 a.m. or later to take that extra hour to pour a few more, said Deputy Chief Brent Clayton. They may not want the extra time in Chattanooga, but Nashville is another story, he said.
"In Nashville, the bars on Broadway are probably definitely taking advantage of it," he said. "They probably don't even like closing down at 3 a.m."
