I work in a team of about 10 people - we all generally get on well but I have a female colleague who fluctuates between being sickly sweet and foul to me. Right now, it's foul and the atmosphere is awful. She is always at the centre of a drama, regularly falls out with others and i find her exhausting.
I've recently returned from something which was a real adventure in my personal life and I think this has triggered the latest episode. (It's something I didn't really talk much about at work but she'd likely have heard on the grapevine.) We have similar life circumstances and I wonder if perhaps she draws comparisons between us, particularly financially. She always notices and comments if I wear new things to work.
I've tried lots of tactics to work with her - being supportive and recognising her input into work projects when appropriate (she's good at her job imo) , in front of her and to her line manager. We have no contact outside work, on social media etc. I try to be friendly in a professional way but have no energy for drama - outside work I'd totally avoid anyone behaving this way but our company is too small for me to do this.
I'm quite comfortable with not everyone liking me. The ones I care about do.
What I'd love to be able to do with this colleague is clear the air, openly acknowledge we're not each other's greatest fans and agree to work together harmoniously but I think that level of honesty might be a step too far. Any advice welcome.
