"Can't be done."
If a subordinate comes to you with a request or suggestion and you dismiss them by saying that something simply can't be done, that is a problem. Such a response kills any future initiative or willingness to innovate. Don't be conservative; instead, always try to find a solution and avoid dismissing subordinates with this toxic phrase.
"You have to …"
When you tell someone that they "have to" do something, you come across as overly authoritarian. There are far better ways to phrase an order to a subordinate. For instance, you might tell them their skills make them the ideal person to handle such an important task.
"That's nonsense."
When a subordinate approaches you with a suggestion, it usually means the issue is important to them and they have a valid reason for bringing it up. While it might seem like nonsense to you, as a manager you need to understand that from their perspective it clearly isn't.
"I don't have time for this."
As a manager, it is your duty to make time for subordinates. If you say you don't have time for something they wish to discuss, you send the message that your time is valuable, while theirs is not. This can seriously damage their motivation and engagement.
