The 22-year-old said she had dreamed of becoming a teacher since age 5 and always knew it would be tough - but said it "could be better".
Simes said every day in front of a classroom was different and she never knew what to expect.
"Some days you can't plan and it goes completely out the window. You're the kids' teacher, parent, nurse and sometimes social worker."
She said most classrooms had 30 kids in them and if children came to school hungry, teachers would find food to feed them. If children were tired they would allow them to nap, Simes said.
"Teachers put their blood, sweat, and tears into their jobs so children can have a good education."
Simes said teachers were just asking for what was fair and to have enough resources to be the best teachers they could be for their students.
She was hopeful people valued the work teachers did and the Ministry of Education would help to get better working conditions.
"If we don't stand up now we are going to lose our new teachers."
