Adele, head of human resources at Techstellung, was becoming concerned about Estelle's work ethic. Estelle had been with the company for five years and had been a competent if not stellar employee. However, following a bicycle accident several months ago, Estelle's attitude toward her manager and her work had changed. For the past four months, Estelle seemed to take short breaks often and no one knew where she went. When she returned, there was a peculiar odor that came from her breath and on her clothes. Estelle's co-workers were complaining that she was not doing her share of the work anymore and they were having to cover for her. Estelle's supervisor recognized the odor as marijuana and tried to speak with her about her behavior. Estelle told him to "take a flying leap of a tall building" followed by some muttered words making rude suggestions.

As a result of the supervisor's report on Estelle's use of marijuana during work hours and his attempted conversation with Estelle, Adele decided it was time to cut Estelle loose and terminate her employment Adele called Estelle into her office and gave her the new that she was terminated immediately because of her conduct, her use of drugs during work hours and her demonstrated lack of respect to her manager. Further, there would be no termination pay. Estelle became very upset and angry and claimed she was being unjustly treated due to her medical condition. Estelle said her doctor had prescribed the use of marijuana to deal with intestinal problems that arose following her bicycle accident and now she was being fired for following her doctor's orders.
