Final answer:
If Barrios had been unable to walk and needed to evacuate the building, accommodations such as ramps and accessible exits should have been in place. The case may not have been resolved before Barrios was terminated or after she filed her discrimination charge due to delays in the legal process and negotiations.
Step-by-step explanation:
If Barrios had been unable to walk and needed to evacuate the building, there are several steps that could have been taken to assist her. Firstly, the building should have had necessary accommodations, such as ramps and accessible exits, to ensure that individuals with disabilities can safely evacuate. In addition, the building should have a designated evacuation plan for individuals with disabilities, which could include the assistance of trained staff or emergency personnel.
As for why the case was not resolved before Barrios was terminated or after she filed her discrimination charge, it is difficult to speculate without more information about the specific circumstances of the case. However, it is possible that the legal process and negotiations between the involved parties may have taken time, leading to delays in resolving the case.
