I'm applying for flexible working for picking my little girl up from school when she starts in September. The school is really close by - if I finish at 3.00 I can't get there in time but finishing at 2.45 will mean waiting around for a while and invariably doing extra work every day (school finishes at 3.15). Can I ask to finish work at for example 2.55? Therefore my contracted hours would be 22 hours and 50 minutes per week. Can I do this? Is it strange to ask?
