“You are unreliable”: how to say it politely
Why it can fall flat
“you are unreliable”
Most people hear “you are unreliable” as a verdict on who they are, so they defend themselves and the real problem gets lost. You likely want missed commitments to stop hurting your work.
Say this instead
- 01
I've had to chase you on the last three deadlines. I need to be able to count on the dates you give me. Can we agree a way to make that work?
Coworker · Chat
Fits a pattern of missed dates, since it names the behavior and its effect and then asks for a fix together.
- 02
The weekly report has come in late three times this month. I need it by noon on Fridays. What's getting in the way?
Someone you manage · Email
Suits a one-to-one follow-up with a direct report because it states the expectation and invites the cause.
- 03
I want to flag that handoffs from Kendall have slipped several times and it's affecting my deadlines. Could we talk about how to handle it?
Boss · Email
Helps once you've already talked to the person and need backing, because it sticks to facts.
- 04
We've now waited past the agreed date for your feedback twice. To keep the launch date, I need your sign-off by Thursday. If it slips, the date will move.
Client · Email
Right for a client whose delays threaten the schedule, since it states the consequence without blaming anyone.
- 05
Third time this week the handover hasn't come through. I can't plan around that. Can you tell me today what you can realistically deliver?
Coworker · SMS
Good for urgent, repeated misses when you need a realistic commitment quickly.
- 06
You've moved our call twice and I haven't had an update since Monday. I need clear next steps and dates to decide how to proceed.
Recruiter / HR · Email
Useful when a recruiter's missed follow-ups affect your decisions, as it asks for clarity rather than an apology.
- 07
Two of your last appointments were missed without notice. Please confirm by Friday if you still want your slot, so I can plan the schedule.
Customer · SMS
Fits repeated no-shows because it is firm and short and gives one clear action and date.
- 08
I need to be able to rely on updates when you say they'll come. Twice this week they didn't arrive. Can we agree how you'll flag a delay early?
Someone you manage · Chat
Handy for a quick, informal check-in that sets a clear expectation about early warnings.
Examples
Hi Ishita, I wanted to raise something about the last three client reports. They arrived after the agreed time, which left me little room to review them. Going forward I need them by 12pm on Thursdays, and a heads-up as soon as you think a date is at risk. Can we talk for 10 minutes tomorrow? Thanks, Avery
Hey Vivek, the design files weren't in the folder by Tuesday, which has now happened twice. I need to know I can plan around your dates. What would help you flag delays sooner?
What to avoid
- Words like always, never or unreliable invite arguments over examples, so leave them out.
- Wait to send it until you can name specific dates and misses, not while you're angry.
- Criticizing in a group channel or copying others in turns a work issue into a public one.
- Burying the request makes it easy to miss, so say clearly what you need and by when.
- A vague “no worries” tacked on at the end cancels the point you're making.
