I agree with Garland on this one.
Also, if a person speaks lies, they will have hatred in their heart, because we are supposed to be kind hearted. Jesus doesn't want us to be angry inside or hate anyone.
I suppose the verse could be paraphrased here as "Whoever lies, hides hatred in their heart."
Even if we don't like somebody, we should still be kind with our actions and words. Honesty is important, but it doesn't mean we will go around and say, "I don't like you!" or, "I hate you!" It's not right. We should be kind to everyone and not hold any hate inside. Of course there will be people in our life we will run into that we don't like, and at that decision we need to be kind, but we need to determine, "Do I need to distance myself from this individual/these people?" or, "Should I witness to them?" or, "Should I continue to be a good example for them?" These are things we need to pray about.
While I haven't read the original Greek/Hebrew version for a more accurate translation, I feel like that specific paraphrasing doesn't work here and defies some kind of sequential logic the verse has.
"Whoever hides hatred has lying lips"
1) "All people who hide hatred are liars." is not the same statement as
2) "All people who are liars hide hatred."
There is a hierarchy. It would be like saying "All women are human beings.", but you couldn't turn it around and say "All human beings are women."
You get what I mean?
HOWEVER, I do still agree with your main point for the most part. Your point definitely still stands, that was just me being pedantic back there. However, people speak lies for a variety of reasons. For example, a child will lie about stealing a cookie because they don't want to get in trouble; a girl or boy can accidentally (like a slip of the tongue that happens before you can think about it) lie to a person who tries to woo them just by saying "I have a boyfriend/girlfriend, sorry" when that's not true. And a variety of other circumstances.
AS FOR THE SECTION OF ORIGINAL VERSE AGAIN:
"Whoever hides hatred has lying lips, And whoever spreads slander is a fool."
This is how I would paraphrase the verse:
"If you are feeling hatred and hiding it, you're a liar. But that doesn't mean you should spread it around."
Being a liar is something that everyone does. It can't be avoided. Why? Because sin. People just can't help sinning, they do it all the time no matter how hard they try not to. Some more than others.
But I believe (yes, this is opinion) that the words of Jesus outweigh the rest of the Old Testament , because he came to fulfill that law and teach new and better ways to act and treat other people.
So yes. Turn the other cheek.
But if you're having a problem with your co-workers, maybe you should confront them out of love (and not hatred) to help make them a better person if they're hurting others, unless it's something really trite or petty, then just let it go. After all, hatred only sows the seeds of more hatred. And which is worse, being hated for spreading hatred and slander around, or being quiet and keeping the admiration and respect of your co-workers?
It's a lot more work to keep hatred to yourself than it is to spread it around, and therefore more respectable. Yeah it's lying, but it's better than starting a hate-war at the office and losing your credibility, which is something that can never be gained again once it is lost.
TL:dr; Turn the other cheek, be a good example to people.
