Hasenwinkel Worked as a Nurse at a Mosaic Facility for Adults

Hasenwinkel worked as a nurse at a Mosaic facility for adults with intellectual disabilities. She took FMLA leave seven times from 2010 to 2012. She was warned that her job performance was inadequate. After exhausting all leave in 2012 she did not return to work and was fired. She sued Mosaic for interfering with her FMLA rights. The district court ruled against her. The court of appeals held that Hasenwinkel:

A) ​had no case because she did not return to work and did not perform her job.
B) ​had no case because she had exhausted all FMLA leave.
C) ​could proceed to trial because the records of some leave were unclear as to the reason for the leaves.
D) ​could proceed to trial because she claimed hostile environment that made work very difficult or impossible.
E) ​none of the other choices are correct.
