How to Tell Your Boss You’re Running Late

Maintaining professional credibility requires prompt and clear communication when workplace tardiness is unavoidable. The objective when informing a supervisor of a delay is to uphold mutual trust and ensure workflow remains minimally affected. A well-executed notification demonstrates respect for the manager’s time and the team’s schedule.

Determine the Urgency and Timing

Communicate the moment you realize you will not meet your scheduled start time. Sending the notification before the official start of the workday is paramount, establishing accountability before your absence is noted. Delaying this communication converts a simple notice into a disruption requiring your manager to initiate contact.

The communication must include an estimated time of arrival (ETA) that is realistic and slightly conservative. Provide a specific time, such as “9:45 AM,” rather than vaguely stating “I’ll be there soon.” Failing to account for unexpected further delays undermines confidence in the reliability of the information provided.

Choosing the Right Communication Method

The medium chosen must prioritize the speed at which the supervisor receives the information, depending on the delay length and company culture. For minor delays, typically less than 15 minutes, a concise text message or instant message is often appropriate. This provides immediate, non-disruptive notice, especially if the manager is frequently in meetings.

Email is the least effective choice for urgent morning notifications, as it may not be checked immediately upon arrival. Reserve email only for delays known far in advance, such as a scheduled appointment running long later in the day.

A direct phone call becomes necessary for significant delays exceeding 30 minutes, or when your immediate absence severely impacts operations. Calling ensures the manager can quickly provide instructions, delegate urgent tasks, or confirm safety, requiring a two-way exchange.

Crafting the Professional Message

A professionally structured message follows a clear, three-part format designed to be efficient and respectful. Begin with a brief, sincere apology and confirmation of the delay, addressing the issue head-on without unnecessary preamble. This directness sets a responsible tone.

The second component is the reason for the delay, which must be vague and avoid excessive detail or emotional language. Use neutral phrases like “unforeseen traffic delay,” “unexpected personal matter,” or “commute complications.” Overly detailed excuses can sound defensive or unprofessional, shifting the focus away from the proposed solution.

The final, and most actionable, part of the message is the specific ETA and a proposed action plan for mitigating the absence. State clearly what time you expect to arrive and briefly mention how you will manage any immediate workload or make up the lost time, such as “I will check emails remotely until 9:30 AM” or “I will stay an extra 30 minutes this evening.”

Example Script 1 (Minor Delay, Text): “Apologies, I’m experiencing a traffic delay this morning and will arrive at 9:15 AM. I will jump straight into the 9:30 AM team check-in.”

Example Script 2 (Major Delay, Call/IM): “I apologize, but an unexpected personal emergency will delay my arrival until approximately 11:00 AM. I have already forwarded the urgent client file to Sarah, and I will work through lunch to ensure my priority tasks are completed.”

Example Script 3 (Known Delay, Email): “My doctor’s appointment is running longer than anticipated. I expect to be in the office by 1:30 PM. I am reachable by phone until then and will make up the time later this week.”

Managing Your Arrival and Follow-Up

The approach upon entering the workplace should be discreet and focused on minimizing further disruption. Arrive quietly, avoiding conversations with colleagues or drawing attention to the entrance. Settle in quickly and immediately begin working on the tasks delayed by the absence.

Soon after settling, a brief, in-person check-in with the manager is appropriate, provided they are not occupied. This is not the time for a detailed explanation, but a moment to quietly reiterate the apology and confirm the plan for making up the lost hours. This follow-up reinforces the commitment to accountability.

Avoid spending time explaining the situation to colleagues, as this interrupts their workflow. The professional action is to focus entirely on productivity and demonstrate that the delay will not impact the quality or timeliness of deliverables.

Strategies for Preventing Future Lateness

Proactive planning is the most effective long-term strategy for maintaining punctuality and professional reliability. Employees should build a minimum 15-minute buffer into their daily commute schedule to absorb common, minor delays like unexpected traffic patterns or parking issues.

Preparing all necessary items, such as laptops, work bags, and attire, the night before reduces the variables that can cause morning delays. Establishing a consistent, optimized morning routine minimizes the mental load and time spent decision-making before leaving the house.

Employees must also familiarize themselves with the company’s formal policy on tardiness. Frequent delays, even if communicated perfectly, eventually evolve into a documented performance issue. Consistent punctuality demonstrates respect for the organization’s time and reinforces a professional habit.
