I'm planning to go back to work early next year and I'm trying to write my boss a letter asking for flexible working hours, i.e. working two full days at the office (per week) and one full day at home. But I just can't figure out how to start the letter and what else I should include. It's really important to me that I get to work part-time as my DC will be very young when going to nursery. I'd be so grateful if anyone could help me out!
