One of your old college roommates, Sandra, is a nurse who took a job that required her to lift 65 pounds smoothly. She was told the job had this physical strength requirement for patient safety and to ensure that teams of nurses could move patients as needed. Sandra worked for a nursing home chain that employed 900 employees.
Sandra had become pregnant and on her doctor’s advice tried to refrain from lifting 65 pounds. After she kept finding herself in situations at work that required her to do this kind of lifting, she decided to just stay home until the baby was born.
After the baby was born, Sandra went back to work, but her baby developed a medical condition that required her to see doctors frequently. Sandra didn’t have anyone else who could be a “dedicated” caregiver for her baby, so she took leave from work to tend to her child.
When Sandra’s leave was about to expire, she asked her doctor to write a note in support of extending her leave. The note wasn’t clear and suggested that the doctor thought it would be nice, but not necessary, for mother and child to be together.
Sandra’s manager told her that the nursing home wouldn’t be able to keep her job open for her any longer. However, he told her she should apply to the company again as a new-hire when she was ready to get back to work.
