True. The practical reality is that it causes colleagues to divert limited resources to address this web of lies. No one wants to do that unless you're a fiend for emotional drama (practically speaking, some are desperate to gather any and all ammo to use against each other). For everyone else, it's emotional labor. And no one is getting paid to do emotional labor (unless that's the unspoken agreement that isn't written in their job descriptions).

If you really wanna out a liar and come out clean on the other end, it's just so much documentation, emotional decision trees, how to phrase & frame & present things, etc. etc. etc.

Often, the compulsive liar will out themselves, create their own demise, or be enabled and further empowered by a toxic system that rewards such types (which if possible, you'd wanna get out of ASAP because prolonged exposure leaves lasting damage to anyone in such systems).
