Hi Sarah,

I’m writing to let you know the northern train line has been suspended due to a signal fault. Rail staff have advised services will not resume for at least 45 minutes.

I now expect to arrive at the office by 9:45am. I have already emailed the client for our 9am check-in to reschedule to 10am, and marked this in the team calendar.

Apologies for the disruption this causes. Please let me know if there is anything urgent I can handle from my phone while travelling.

Regards,

My car broke down on the highway 15 minutes ago. The tow truck is currently en route, and I have booked an Uber to take me directly to the office once my car is collected.

Sorry for the inconvenience this causes today.

Apologies for this unplanned disruption.

Frequently Asked Questions about Sample Letter for Coming Late to Work

When should I send a late to work letter?

Send the notice as soon as you discover you will be late. Always notify your manager before your scheduled start time if at all possible. Even for 10 minute delays, a quick note is good practice.

Do I need to explain exactly why I am late?

You only need to share relevant, factual details. You do not have to share private medical or personal information. Stick to the cause, arrival time and work cover arrangements.

Should I send this as an email or text message?

Always use email for official late notices, this creates a written record. You may follow up with a short text alert for very urgent delays. Never use only social media messages for work notifications.

How formal does this letter need to be?

Keep the tone professional but natural for your workplace. Avoid slang, excessive excuses or over-apologising. A clear, polite note is always appropriate regardless of your relationship with your manager.

Can I use a template for every late notice?

Yes, you can use a base template, but always customise it for your specific situation. Generic copy will come across as insincere. Add one specific line about your work arrangements each time.

What if I don't know my exact arrival time?

Give your best honest estimate, and note that you will update if this changes. Never guess an early arrival time that you cannot keep. Update your manager again as soon as you have new information.

Do I need to make up time for being late?

This depends on your company policy. It is good practice to offer to make up missed time voluntarily. This shows accountability and respect for your team.

What if this is not my first time being late?

Acknowledge the pattern politely, confirm you are taking steps to fix it, and do not make excuses. Taking clear accountability will go much further than multiple apologies.

Every employee will arrive late to work at some point. How you handle that moment matters far more than the delay itself. Using these sample letters will help you communicate clearly, take accountability, and preserve the trust you have built with your team. You can adapt any of these templates to match your workplace culture and specific situation.
