Last month, the government made changes so head teachers can no longer allow absence outside school holidays, unless there are exceptional circumstances.
It's because of concerns that some kids were missing school for family holidays during term time when it's cheaper.
But more than 125,000 people disagree, signing a petition against the move.
The petition says: "All children who have a good attendance record should be allowed the opportunity to enjoy quality time with their parents on an annual holiday of up to 10 days once per year."
But the government says it's giving schools more freedom to set term dates - which could mean parents could book cheaper holidays.
Ricky's got the story.

The Welshman, 31, led Team Sky in the Giro in May, but his hopes were ended when a police motorbike caused a crash on the Blockhaus climb on stage nine.
Thomas was forced to withdraw from the race, but he is fit to support Chris Froome's bid for a fourth Tour title.
The Tour, which begins in Dusseldorf in Germany, runs from 1-23 July.
Spaniard Mikel Landa, who was also involved in the crash at the Giro but recovered to finish 17th, is also in the squad.
Britons Ian Stannard and Peter Kennaugh are notable omissions, along with Wout Poels.
Dutchman Poels, who played a major role in Froome's victory 12 months ago, suffered a significant knee injury in February and only returned to race at the Route du Sud earlier this month.
Stannard and Kennaugh were both in the Sky team in the traditional Tour warm-up race, the Criterium du Dauphine, but have been overlooked in the final selection.
That means there are three Britons in the squad, with Froome and Thomas joined by road captain Luke Rowe.
Froome is aiming to win the Tour for a third straight year, and fourth overall, following victories in 2013, 2015 and 2016.
"We're ready as a team and I can't wait for the Tour to start now," said the 32-year-old. "Honestly, I just love it. It's a feeling that you don't get from any other race."
Team: Chris Froome, Sergio Henao, Vasil Kiryienka, Christian Knees, Michal Kwiatkowski, Mikel Landa, Mikel Nieve, Luke Rowe, Geraint Thomas.

His name is most closely associated with nationalist Egyptian President Gamal Abdel Nasser in the 1960s.
Mr Heikal was the editor of Egypt's state-owned newspaper, Al-Ahram, during that time, articulating the Nasserist ideology of "Arab socialism".
He also served as information minister and briefly as foreign minister.
Following Nasser's death in 1970, Mr Heikal was sidelined by his successor Anwar al-Sadat. And in 1981 he was jailed along with hundreds of government critics.
He was released by Hosni Mubarak after Sadat's assassination by Islamist militants later that year, but was kept at arm's length by the president throughout his 29 years in office.
But Mr Heikal remained for decades one of the most authoritative commentators on Egypt and the Arab world - as well as a historian of the tumultuous events of the Nasser area.
Announcing Mr Heikal's death on Wednesday, Al-Ahram said he been ill for three weeks, and had suffered fluid on the lungs and kidney failure.
President Abdul Fattah al-Sisi paid tribute to Mr Heikal, calling him a "journalistic icon", while the cabinet said he had "massively participated in enriching intellectual life with his books, articles, political and historical studies", Egypt's ON TV Live reported.
Your next holiday might seem like a long way off but there's a row brewing about when schoolkids in England should be able to take them.
