How do you deal with fake people?

There this lady at work called Karen (enough said) at first I really thought she cared and that she was one of the good guys at work. there's always been a lot of toxic females at this work place. Full of bitching, gossip, fighting etc. We'd always laugh at the mean girls at work and we both agreed we didn't like that kind of behaviour from other females or are self's.

I thought she was better than that and Didn't get involved in the bullying at work and she acted as if she was taking me under her wing. I honestly feel as much betrayal as Harry Potter did from Dumbledore 😅.

I will admit I struggle at work and I'm not prefect but I'm getting better just I have some bad days at work like anyone else and make little mistakes that are easily fixed. When she finds out about this instead of helping or focusing on her own job she runs off to tell my manager and bitch about me to my colleagues.

There was a another colleague before called Tammy who was a massive bitch and she had her little minion Indy who's ment to train new people but Instead picks favourites and doesn't do any work. She makes bigger mistakes than me yet makes a big deal when I get a label the wrong way around. Tammy was moved to a different shift for bullying and now Indys came crawling to Karen side to be her new little minion and Indy doesn't like me much at all for pretty much no reason and she eggs on Karen to bitch about me and try get me fired because Indys to thick to blot against people herself.

Karen has now said she's not gonna work as hard because I'm doing less work than her and we get paid the same. How does she know I'm doing less work than her unless she's spying on my work and going through my paperwork instead of focusing on her own work. I've been here 5 mouths she been here 7 years of course I'm not gonna be at the same standard has her and she's injuring herself because she works dangerously just to get on top of other people.

she's so nice to my face. She tells me I'm doing great and I'm too hard on myself and but everyone wants me to do well and then tells others she wants me gone and im stupid. Also I was sexually harassed at work not too long ago and another colleague who witnessed it reported it. She told everyone I was lying including my manager when it wasn't even me reporting it and now she's making out like I falsely accuse men yet didn't have the guts to say this to my face. She's so manipulative

I can't get my head around it. I don't have time to be cruel about others at work. I keep my head down and focus on my own work. I'm on probation right now so I can't confront her and others have told me not to because she's got my manager of wrapped around her little finger. I go work to make money. I don't have any interest in being mean about people. I don't have it in my heart to treat others like that. If I have a issue with people I avoid them not try to be there friend
