@sre123 I think in the UK, the people at the top see the numbers and think 'i had a caseload of 30 in the 80s, so they've got 25 it's fine'. But the complexity and the amount of work required (eg since moving from paper files with brief handwritten notes to electronic with teams of reports to complete) is huge.
When I started in practice, cases of sexual abuse were rare, and only held by the senior social workers usually. When I last managed a team, every single person on the team had at least one sexual abuse case, including those just qualified. When I started I had mostly 'child in need' cases. Nowadays, the families that I worked with at that level would be with 'Early help' teams, and almost all the work on the social work teams are child protection and court level. Technically child in need is still a social work, not family support, role but the thresholds have shifted a lot.
While I don't know social workers who take children out for the day, I do know plenty who spend a lot of time with them and take them out - but it's invariably those who are working 20hrs+ of unpaid overtime a week to get it all in, hence the good ones leave and go to roles with a better work life balance. It's really sad that we give safeguarding such low priority here, and the consequences, as in poor Sara's case, are horrific.
