How do full time working parents take their kids to and from school?

I was just wondering how does that work if both parents have full time jobs and you work at like 7:30a or 8:00pm? Or if they are out of school by 2pm but you get off at 5. Obviously if you have relatives to help that would be best but not everyone has family around. What if you don’t trust hiring some person to do it even from a reputable agency?

I don’t have kids yet but thinking about it already concerns me lol.
