Some social workers get my sympathy hc, not all, there are good and bad. Have seen some horrific cases where social services were useless and some where they were wonderful. It often depends on the borough. There is one borough I actively shudder at when i get a referral from as it never anything other than 'complex'.
And my jobs not emotional Boobies, I don't deal with the kids, I just make sure they get seen and people do what they say they are going to do. By the time they get to me it is hopeful because whatever it is will hopefull stop and we will get them on the right track. It's a positive job, not an emotional one :c)
