if you have four children between 6 and 16 you will receive an exemption from looking for work until your eldest child turns 16 - on that date (or when your exemption expires), you will have that exemption removed and will be under the same mutual obligation requirements as any other single parent. you mutual obligation activity is negotiated with c'link and may be work/study/training/volunteer work (with an approved organisation) for 15 hours per week, or, if you're not engaged in any of these, you wouldbe expected to be looking for work to meet these obligations
