<human>: My girlfriend works for some woman in a chiropractic office and the lady has just been horrible to her. My girlfriend is not disrespectful or lazy or anything and is pretty much a pushover. Her boss yells at her for mistakes not even her fault and is now calling her names and spreading rumors. My girlfriend doesn't even want to say anything to me about it and I force it out of her because it isn't right. Today she just came home and told me that her boss told her fellow employee's that my girlfriend had a "learning disorder". She is also making her work Saturdays now but when she was hired, they both agreed it was a Monday to Friday job. Here's what happened with the Saturday situation. Her boss came to her and said "Can you work these next 5 Saturdays for "so-and-so"( I don't know her name) because she can't work them. My girlfriend said "Sure. Only these 5 Saturdays and I'm done though, right?". Her boss "Yeah.". It's been 6 Saturdays now and she is about to start her 7th Saturday tomorrow. Is this something she should go to a lawyer about. Because apparently this isn't the first time she has called her names behind her back to other employees and my girlfriend just can't quit?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Can your boss call your "laerning disable" and make you work shifts that you can't not work and didn't agree upon with no consequences? Is it something to talk to a lawyer about?
