This approach gives them a chance who seems to be hiding some information. 

You ask for their confirmation to decide what they believe about their information.

5. “Let me be honest with you, and tell you that I don’t think this will work.”

So you tell them that you don’t believe their plan or suggestion. 

That you need another suggestion or new proposal from them. 

6. “Well, I find it quite hard to believe. Please, can you explain it in more detail?” 

You can’t work on the data or information that is based on guesses. 

So, you tell your employee or coworker to provide you with more detail and explain the case briefly. 

This is a better approach than calling your employees or workers liars. 

7. “I don’t know anything about it. So, it’s better if I stay away from this.”

And so you make it very clear that you have no idea, what these coworkers are up to. 

But you already know they are lying about something.

You are allowing them to resolve their mistake if they have lied unintentionally.

This is a formal response to show that their past statement and promises don’t match the results they are sharing now. 

10. “Thank you for the information, but I’m having some trouble relating to your point.” 

Your main trouble is that customer who is hiding some information with you. 

But being polite you tell them that you can’t relate with what they say to you.

You suspect that in your team that employee is lying and trying to trick you.

Whether it’s related to handling internal conflicts or the accusations they made about others, you have to make the decision considering everyone’s experiences and opinions. 

It might be too early to call someone a liar without knowing much about it.

15. “I think that’s enough information. I will update you on this after some fact-checking.” 

Instead of accusing the client of lying, you tell them that you need some time to verify their details. 

You could also say ‘I will get back to you’, to do some research yourself.

16. “I hope you are well aware of how important it is to be honest in this situation.” 

This is a polite approach to asking for validation from someone lying at work. 

You are giving them a chance to correct their information or statement.

And you hope that they will confess that themselves. 

17. “Thanks for the suggestion. But let me know, how sure are you about this?”

Their suggestions or recommendations don’t seem credible to you. 

So you tell them to revisit their plan and check if this is workable or not. 

18. “I hope that you know the urgency of this situation and that you are taking full responsibility for it.” 

When you tell them that they are responsible for the results, they are more likely to accept that they are lying. 

If not then, they take more time to correct the false information.
