Level 3 TA here, primary school. I work 32.5hrs a week, take home pay just over £1k a month.
Arrive at work at 8:20am, set up the class for the day. Do several focus based tasks with groups of children throughout the day. I do daily interventions with children with various learning issues/needs as well as the initial assessments. I'm wholey responsible for this (I feel the pressure!). I've got a lot of additional needs children under my wing and frankly find the intervention work a job in itself without being a full time TA too!
30 min for lunch which is usually shaved short due to being needed somewhere and getting pulled aside while I make my way to the staffroom! Yard duty for breaks and lunch time. Major crowd control skills needed here! 
I also cover my teacher's PPA session so I'm left alone in class for one morning/afternoon each week. I have to participate in the weekly planning meetings with teaching staff. Forever being pushed to do additional training and courses. We must be constantly working to improve and better ourselves and this has to be evidence based and it's pulled up during staff appraisals if we fail to provide evidence.
Most of our additional need children don't have statements. It can be really tough (on everyone) especially for those who would benefit greatly from 1:1 support. Sadly lack of funding just won't allow it.
Blanket rule that no staff has time off unless medically needed (and this must be evidence based), so school shows, Christmas plays etc is a big fat no.
My workplace certainly feels 'understaffed'. Often feel like we are just chasing our tails and rushing in a desperate attempt to get everything done. Every TA in my school feels stressed out and overworked on a daily basis pretty much.
I arrive home every single day and collapse on my sofa in a drained and exhausted mess.
I'll end on a positive note
Our teachers worship us, truly. I'm told often how valuable we are and how much they depend on us to keep the place going. Seeing children progress is brilliant. Other than the odd cutting out/laminating/preparing I leave my work in the workplace. Evenings and weekends are my own. The holidays are ace!
It's a rewarding job, but it's tough. Really fucking tough.
