Reimbursement email template
Subject: Approval request — AthlyticZ workshop: From Scripts to Package: Building Reusable Python Code Hi [Manager], I'd like to enroll in "From Scripts to Package: Building Reusable Python Code," a live 3-session workshop from AthlyticZ (Sep 7, Sep 8, Sep 10) led by Joseph Barbier. Across three sessions you'll turn a messy analysis script into a clean, tested, documented Python package your team can pip install. It is directly relevant to my work, and I'll finish with a concrete deliverable I can bring back to the team. It includes live instruction, lifetime replays, and a provisioned enterprise Posit workspace. Could this come out of our learning and development budget? I'm happy to forward the receipt and a certificate of completion. Thanks, [Your name]
