It's one of those roles you have to weigh up the pros and cons of really.
Pros are that you should be able to work to rule, mostly; in a way a teacher cannot (there are things like marking that are simply part of discharging their professional duties) - save for the odd bit of laminating at the end of your break before the bell goes you shouldn't really be having to go too above an beyond.
It is a shortish work day compared to someone who starts at 8:30 and is thinking about leaving the office at 5:30 pm. You are paid accordingly but should be able to plan your family life or just your life in general around this. For some people, it would mean they could go to the gym 5 days a week or socialise when they otherwise could not, but it's easy to take it for granted when it becomes your normal work day.
You can park your car on site. Nurses and health care assistants in hospitals can sometimes be on similar payscales but don't have this perk. In the same way dispensing chemists (from the other thread about pay) don't necessarily if they work in a city centre chemist.
Personally I work in an office in a school and that's perfect for me. It's more my kind of work and I can eat drink and pee when I want. I don't have to go outside in the elements, work very locally to where I live, can park my car outside my office window and it's like being part of a big family. I could earn more money in a different office job, but I get all the holidays and I'm out the door at 4pm so it's just great, and you still have that feeling of making a difference and helping people in a community-focused role.
I think LSAs can get "stitched up" easily - sorry, you're not going to the farm today, you have to 1:1 this kid because his 1:1 is off. Or sorry you have to do forest school, shame you wore your nice shoes and blowdryed your hair this morning. Oh and next year we are putting you in that class with that teacher and those pupils, etc.
The tension felt at the time of year when SLT have decided where to put whom and haven't yet told them is really something. I love knowing what my workstream will look like!
I'd like to see all school support staff on at least a scale 6 but really the thing holding the pay back is the hours worked - with the short day and the long holiday, it's always going to be part-time.
But you never have to work weekends or Christmas day or shifts for that matter and I do think that's what's stopping most heading to retail jobs...
