I think that it depends very much these days on the school that you work in. Your current school sounds relatively sensible, with work load that is manageable. However, be very very careful as that is rarely the case these days.
Last year I worked in a primary that had a hideous workload. I've been a teacher for 20 years, and the last few years saw huge changes. Yes, in the past 10 years we've always had pressures on data, but this was something else entirely - every 6 weeks you had to produce a data pack which analysed progression and attainment APS in minute detail - various groups had to be analysed - FSM, school action, school action+, boys, girls, slow movers, different intervention groups, and you then went to a meeting armed with the data ready to defend every child's data with notes on what you had done to ensure accelerated progress. It was also a school where every Friday ALL books and planning had to be left out for SMT's scrutiny. Planning had to be completely individualised with colour coded key questions for individual differentiated groups, each lesson being like an essay/script. It then all had to be annotated with quotes from children and analyse of how lesson went, and how it then affected your next lesson. And you had to do lesson plans for your TA. Children with misconceptions or difficulties had to be individually highlighted, with information on what their gap risk would be, completed before the next teaching session. This was for English, maths, mental maths, guided reading, and phonics DAILY, and Science and non-core weekly. This was on top of a very complicated marking system, where every piece of work had to be marked with a comment and next step, which every child had to respond to, and then you had to acknowledge their response. And there were weekly 'class room environment' checks - working walls (maths, English & science) and target displays, which had to be changed weekly. All of this was closely monitored with constant threats of capability if any of your standards slipped. That was not a school I wanted to work in.
I now work in a sensible school, where planning is detailed and scrutinised, but not nearly in as much depth, and teachers professional judgement and knowledge of children is taken into account without everything having to be evidenced on paper. Data is analysed once an old term, and the meeting is a supportive one, with all parties genuinely engaged in thinking of ways to help children whose progress has slowed. The marking policy is heavy, but not overwhelming.
So... Choose your school carefully. It makes a MASSIVE difference.
