Sample Letter for Unprofessional Behavior: Addressing Repeated Late Arrivals
Subject: Concerns Regarding Attendance – Immediate Attention Required
Dear Alex,
During the past month, there have been five instances where you arrived late for team meetings at the main office—specifically on May 3rd, 7th, 12th, 18th, and 23rd. These delays disrupted project discussions and set a tone of informality that conflicts with our company’s punctuality policy. Our team expects all members to be present at the scheduled time to maintain productivity and mutual respect.
We understand that unforeseen circumstances can happen. To address this, we propose the following plan: first, you’ll sign a brief time‑management pledge, and second, you’ll complete the introductory training on efficient commuting strategies by June 15th. If no improvement is observed, we’ll need to move to a formal performance review.
Please let me know if you’d like to discuss any challenges that might be affecting your punctuality. I’m confident that, together, we can resolve this promptly.
Thank you for your immediate attention.
Best regards,
Jordan Lee
Human Resources Manager
