Not sure if this is the right place to put this, but I've been working with my husband for nearly a year in a warehouse and we get on quite well but a female from the office has been trying desperately to get his attention the whole time I have been there! She has now taken to lying about me to anyone who will listen (bosses and people I hardly know or see!)I have been getting nasty glares off people and ignored ,eventhough I have said or done nothing wrong to any of them. she is now pretending to date the bosses' son and they are both trying to get me out by making me feel uncomfortable She keeps saying older men (over 50) keep asking her out on dates my husband is 53 she is 23 and claims to not be interested in her! He does admit to talking to her before I went there (his idea btw ) she makes sex noises in front of everyone and is constantly lurking around where ever he or I work (sometimes together sometimes not) )she keeps telling people she wants a long term relationship as she is never exclusive in her realtionships!!! I am worried I am going to lose my job because other people (mainly men) like her and some don't talk to me anymore because I stay away from her unless I have a reason to talk to her(always polite)! The longer I have been there the worse it has got. This is my only job and my husband likes me being there, I enjoy the job. What can I do to stop her lying about me all the time!? What is her problem!? She was shocked when she asked me how long me and hubby had been together (over 30 years!). The look on her face was like a slapped bum! She has been trying to get his attention ever since!

What lies has she told and how is she and the bosses son making you feel uncomfortable?

What do you mean by your husband used to talk to her?

I should point out that she told her 'just for show bf(bosses' son) that she wants kids in the next 3 to 5 years and claimed a married over 60 year old trainer at work made a pass at her, it seems to me that she thinks she can get my husband for herself if I am fired out or am made to leave . It was his idea for me to work there! He said if I go so will he. She shows no interest in the lads her own age but is often trying it on with the guys over 30 especially if they are married, she keeps claiming that the older ones are looking at her breasts and keep asking her out for a drink.

she told people I shouted ate her when I didn't. the bosses son is one of the ones who glares at me. My husband he used to talk to her if he saw her (he is polite),now he generally only talks to her for work and she doesn't like that

Your husband is not some vulnerable animal that has no say in his own actions. I could have Brad Pitt naked and on his knees begging for a shag and I wouldn't entertain him and cheat. Bar some ridiculous statements that she may or may not have said, I don't know why you care?

I care because I don't want to lose my job when I have done nothing wrong

She sounds very annoying and immature, all talk about how men like her, in her opinion! she must be very insecure.
Annoying as it is, just look very disinterested and only speak about work, perhaps she won't stay at the job long anyway?
