You do not need a farewell speech.
You need a date they can use.

You have decided to leave. The draft keeps turning into an explanation, an apology or a list of everything that went wrong.

Give each document one job. The letter states your decision and last day; the handover note names the work and its next owner; the record captures what you sent. Four working sheets, an annotated fictional letter and focused examples help you prepare those pieces without turning the resignation into a memoir.

• Build a short letter around the role and last day.
• Choose whether a reason or thank-you belongs.
• Write a handover someone else can use.
• Check the channel, copy and final version before sending.

Confirm the requirements and intended date first. Then fill the letter frame with facts, not a history of the job.

A writing guide, not employment-law advice. Notice obligations, delivery requirements and consequences depend on your circumstances; verify them before relying on a date or sending the letter.
