In the majority of cases if you have a child under the age of 18 then you have a statutory right to request flexible working. Your employer can only reject your request on the grounds that it would adversely affect the business or incur a great deal of expense.
Even if you have a right to request flexible working you will want to think carefully about what kind of pattern you want to request and how you approach your employer. In particular you will want to consider what is practical for you, what is practical for your employer and recognise that some degree of negotiation may be necessary.
