If you want peace always avoid office politics at all.

Just ignore her and her character..you will come off it.

No need for explanation to the people who know you. Let her beg from the ones she gossips to. Keep your peace, but never let anyone overstep

Propose to her, so that you don't give her things for free of charge

Pencils, erasers, hole punchers, etc., are equipment company should provide. However, for groceries, I would ask her for money ahead of time and stop... carrying extra cash with you. Tell her your credit card is missing and you can't charge it. Provide a tally of the things you have bought so far and be assertive and ask for the money back as you are short this month....
There are many ways to combat these scum bags.

Take it to leadership and ask them for a mediation between the three of you. Bring every receipt from all you’ve done and name names. Do this request... via email and cc all pertinent people. Site any policies from the employee “handbook”, if it exists.  more

Just say "NO!!!" to things she wants you to do. Eho cares what she says to others.
Tell her that you just don't have the time to help and then... direct her to other resources.
- Let her know that she can ask her supervisor for the supplies that she needs to fulfill her role.
- Tell her about the apps that she can use to order her groceries online and have them delivered to her.  more

Please, if with all the good things you did for her she is not pleased and now she is talking behind you. OK, tell everyone about what she used to ask... you and explain to them because you refused to continue with her demand, that is why she is backbiting you. more

Hi,

I am sorry you are dealing with this situation. I always recommend employees to be empowered by first having a conversation with the individual... to let them know how you feel about the situation, and how it is affecting not only you, but the entire work department. If they are not receptive to having a conversation and the behavior continues then escalate the matter to HR. A stress free environment is needed for productivity, better workplace culture and environment, and mental health.

Good luck! more

Your true value is intrinsic (inside you); her perception of you is just a reflection of her own limited myopic vision.

tell her depending on others is cheap mentality ,begging is totally cheap,free mentality

She does not define you,so whether she thinks your cheap ,that is her not who you are. Concentrate with your work. Next time she borrows something dnt... give her. I had this policy that I dnt share anything in the office so if for any reason I gave you anything you knew it had to come back coz there will be no next time if you don't. Set your boundaries and dnt let anyone cross. Sharing is not bad but not to a point it's inconvenient to you. more

Use your Emotional intelligence

She knows you are not her assistant, so no need to tell her that. Just say no...whatever ending that is appropriate. Now that she is bringing other... people into the mix, I agree it's time to discuss with leadership. You two are coworkers so this situation must be handled with care... more

you should just clearly communicate to her that you are not comfortable with what she does, and inform your immediate supervisor.

Accept you are cheap and concentrate on your work.

You can flatly openly refuse her. She is taking advantage of you. Mind you she won't stop

Tell her you’re not her assistant and inform a supervisor
