They say
What to say when an employee says “That deadline was impossible.”
When an employee says the deadline was impossible, examine how the date was set and whether it was realistic, then ask when the employee recognized the risk and what they did about it.
Your response
“It may have been. Tell me when you first knew the deadline was at risk and what you did then. We also need to look at how the date was set and whether it was realistic.”
First, check this
Did you set or accept the deadline without enough information about the work, dependencies, or competing priorities?
Why this works
Two questions matter: whether the deadline was realistic and whether the risk was raised early enough. The manager may have imposed an impossible date, while the employee may still have waited too long to say so. Examining both prevents the conversation from becoming an argument about blame and produces better estimates, commitments, and warnings next time.
Don’t say
“You agreed to it, so it couldn’t have been impossible.”
If they push back again
“I did tell you it was tight, and you said do it anyway.”
You could say
If I did, then part of this miss is mine. Let’s check what was said and when. Next time, bring me a revised date or a smaller scope, and I’ll take it seriously.
After the conversation
- Agree on how deadlines will be set from now on, including who estimates the work and when a risk must be raised.
- If you set or pushed the date, tell the stakeholders affected that the planning failure was yours.
- Record how long the work actually took, so the next estimate can start from real numbers.
Questions managers ask
What if I set the deadline without asking how long it would take?
Take responsibility for the date as well as the miss. Tell the employee the deadline was set without their estimate and that you’ll ask for one next time. Their late warning still matters, but owning your part keeps the conversation from treating your planning decision as their performance failure.
How should employees push back on a deadline they think is unrealistic?
Ask your team to raise it early and to bring an alternative. “I can finish by the 14th, or by the 10th without the testing” gives you something to decide. Tell people this is what you want to hear, then react well when someone does it, or nobody will warn you next time.
Is missing an impossible deadline a performance issue?
Missing a date that genuinely couldn’t be met is a planning problem. Staying silent about the risk until the last moment can be a performance problem, so judge the two separately and take each up with the person responsible for it.
