I work 3 days a week in a senior role. The job was originally advertised as full-time with flexibility, and the boss asked what my ideal was - it was then 3 days a week and they obliged, but have since taken people on.
Looking ahead to when my DD starts school in Sept, I'll be able to work 4 days and would like to ask for that. I think the company will want/need that - but don't want to assume, or come across as entitled. For context, I'm doing well in the job and had a very positive 1-year review.
How should I word the email expressing my new availability to the boss? thanks!
