my sister is young, she just started back to work (retail) from her maternity leave. and she pumps for breast feeding, she works in retail and her boss if giving her a hard time when she needs to pump. she said she pumps right before her shift starts, on her break, but sometimes is full before the end of her shift. her boss has been harsh with her about asking to pump and tells her she needs to do it on her break (which according to her word she does.) what are the rules that go along breastfeeding and breaks?
