Do I need to give a reason for requesting part time hours?

You are not legally required to share personal details, but providing a clear reasonable reason greatly increases approval chances. Only share what you are comfortable disclosing.

Employers can refuse requests only if they have a valid business reason such as inability to cover workload. They must respond to your request in writing as required by local labour laws.

Should I talk to my manager before sending the letter?
