A Florida teacher has a battle ahead of him. Robert Goodman was diagnosed with colon cancer. He has had to go through surgery and chemotherapy.

The treatments used up all of Goodman’s sick days, and he thought he would need at least 20 more to complete his chemotherapy.

The Palm Beach Gardens Community High School history teacher reached out on Facebook, asking for help.

Other teachers, staff and administrators who all pay into the Florida retirement system gave not only 20 sick days, but 75 days to help Goodman take the sick time he needs, CNN reported.

"Educators all over the country were reaching out to me to donate their sick days, even professors over at Florida Atlantic University," Goodman told CNN. "I felt guilty because I knew there were people who had it much worse than me."

But it wasn’t only the other staff members who answered Goodman’s call.

"Students sharing stories of how I've positively influenced them was a good reminder of why I chose to teach and why I can't wait to get back," Goodman told CNN.
