I am responsible for the care of my son (4 years 4 months) and my newly born daughter (3 months), and my wife wants to start part-time work. In order to meet my childcare responsibilities (school drop off and pick up, helping with homework, doctors' appointments for my daughter etc), it would be too physically demanding, emotionally draining and inconvenient for me to work full time while bringing up my children.

Specifically, I would like to work a 2 on and 4 off shift pattern, and would be willing to job share.

I look forward to hearing from you.
