St. Clair, who lives in Corona, California, is scheduled to work Wednesday from 7 p.m. to 3 a.m. She'll return Thanksgiving Day before 9 p.m. and work until 5:15 on Friday morning. She has to sleep at some point, so family dinner is out.
She likes working for Target, which is why she has stayed with the company for six years, even after relocating from the East Coast in 2011, she said.
St. Clair's also grateful to have a job that pays time and a half plus bonus pay for overnight hours, even if it means she can't fly home to her own family for the holidays.
But after watching Black Friday sales start earlier each year, she decided the company had gone too far this time and started a Change.org petition asking Target CEO Gregg W. Steinhafel to forgo the plan to open stores on Thanksgiving.
"I wasn't too happy about going in at midnight last year, but when I found out we were starting on Thanksgiving night this year, I thought enough is enough," St. Clair said in a phone interview. "It's one of few days retail employees get to spend with their families, but at this point there's no time to see family."
She's not the only one who thinks the "Black Friday creep" hurts employees and their families.
More than 40 petitions have been launched on Change.org asking retailers including Sears, Target, Walmart and Kohl's to "give Thanksgiving back to families." Many of them popped up after St. Clair's appeared Friday, earning more than 200,000 signatures as of Wednesday.
When it started earning traction, Change.org promoted the petition among users, but even before then it had taken on a life of its own, site spokeswoman Charlotte Hill said.
"Employees and customers alike are saying, 'Thanksgiving should be about celebrating with family, not shopping for the latest deals,' " Hill said.
Comments on the petitions echo that sentiment, with some threatening to boycott stores that they say put revenue before employees.
"I'm a conscious consumer; I think of good reasons to shop where I do, and consider why and why not to give any store my money. Seeing this happen year after year to the employees of Target irks me, and makes me want to ... take my money elsewhere," one user said.
Other comments in petitions against Target and other retailers focused on the importance of letting employees spend time with family.
"After 33 years in retail, I still love everything about the holidays....except telling some poor employee she has to forgo her family holiday because she has to work! We really have to put a limit on the madness!" said a person who signed a petition titled, "Retailers: Stop Black Thursday."
"Families should come before retail sales! Give these people the day off that they deserve," said another person who signed the petition "Wal-Mart: Move Black Friday Start Back to Friday."
Relatives of retail employees are also speaking out. The sister of a Target employee in Illinois started a petition on behalf of her family, claiming that for them, Thanksgiving will "not be complete" without him.
"Family has always been important to me and Thanksgiving is all about family," Jennifer Ann said in her petition, "Target: Don't take away Thanksgiving." She asked to withhold her last name in deference to her brother, who asked to conceal his identity.
Last year, it was hard for her 24-year-old brother, who has worked for Target since high school, to relax knowing he had to be at work, she said in an interview with sister network HLN. He rushed through dinner and had to leave for his shift just as everyone was starting to unwind.
