As employment lawyers, we often get involved in cases where applications for flexible working have been rejected unfairly or where employers haven't followed the procedures. A carefully considered initial letter, however, should ensure your application is considered as fairly and reasonably as possible by your employer. In the unfortunate event this isn’t the case, it may then form an important foundation for any claim you might pursue. Knowing where to start in any flexible working application can be difficult. We’ve used our experience to put together this self-service letter as a starting point.
