Job question. friend had situation @ her job wants advice. she works @ a nursing home as a nurse aide.?

she has in the recent past gotten in trouble 4 spending a lot of time talking 2 the receptionist on duty. abt a month ago she was told that if it happened again shed be fired. since then has improved. so anyways, the other night @ work she was sitting w/ the receptionist 4 abt 15 minutes, both on the phone w/ her husband (five minutes) & the rest of the time calling 2 remind her patients of dinner, ect. @ this point 1 of the patients called 4 help 2 get up, but she is pregnant & dr says she can only lift 25 lbs. she told other worker that was there w/ her that she could help her w/ the patient, but not lift her. the other worker then started yelling, saying what the hell good r u then, ur going 2 get fired from ur job if u cant lift...when she said that she could still help just not lift, the other girl said get the hell out of here. girl then called boss, 2 tell abt her sitting. even tho most was spent working. friend worried abt losing job, but also mad that girl yelled @ her.

so then my friend & girl didnt talk anymore just ignored each other. my friend went on lunch & the girl came in 2 yell @ her again! calling her stupid lazy right in front of a nurse who just sat there. so then my friend tried 2 call boss 2 tell her other girl wouldnt leave her alone. no answer so left message. my friend very upset abt girl accusing her of spending 20+ mins @ desk so wrote boss letter explaining her accusations were untrue, & that the girl kept yelling @ her. sorry so long! what friend wants to know is should she be worried?? & shouldnt the other girl get in trouble 4 yelling @ her? oh, one more thing. boss said shed handle it tuesday but she was working today and so was friend and no one said anything to her. friend was too afraid to mention it. wants to know opinions suggestions advice, ect

if she brought in Doctor's orders she can't be fired...if not she needs to get one in as soon as possible.
She also needs to talk to her supervisor about the harassment on the job It's against the law
