Lots of you probably see lollipop men and women on your way to school. They help you cross the road and keep you safe.
There are worries however that fewer and fewer people want the job, and that the shortage could be putting children's lives at risk.
It's thought people don't want the work because it's part-time and you don't get paid very much.
Schools are now trying hard to get more new lollipop men and women working.
Around 4.2 million children use school crossings everyday. Lots of roads are now without a lollipop person, meaning that sometimes children have to cross busy roads without help.
