Furthermore (as I'm on my soapbox now), of that £20 about 3/4 goes on our wages, of which we pay nigh on 7% superannuation (because we were never "allowed" to pay more than an additional 3%) and the rest goes back into the system as PAYE amongst other things. So, in effect, "I" get less than £10 to look after your child each day. Some of your children, and indeed yourselves are tiresome, worrying and stressful little tinkers which most of the working public would not tolerate but which we have to since we are "public servants".
And now, the wonderful private sector (of whom bankers are a shining example) want us to look after their deviant little children even longer, pay more into the system and work until a time closer to our moment of earlier-induced-death.
I love my job. And for the record, I and a significant number of my colleagues shan't be striking on Wednesday since, in spite of my rant, it seems entirely wrong to us to withdraw your children from what we have to offer and simultaneously making your day harder to bear especially in these times of financial strife.
