Topic 1:
The rule is that you cannot use stereotypes about age in general vs the actual abilities of the applicant except if there is some condition that cannot be detected but absolutely is age related.
Are there any jobs that you would absolutely not want a certain-age person performing? For example, an 85 year old bus driver for your young kids or a 18 year old as gun carrying policeman? Alright, I found the two easy ones. Can you think of any other jobs where any one "that" age should not perform?
Topic 2
You are the HR Director for a business that provided advanced and precise manufactured safety parts to the auto industry. All employees have engineering degrees of some sort. Your data analytics are showing high error rates during the 2nd shift. You drill down and discover the errors are coming from one of two workers, Marley and Jesus. You call Marley and discover he is a obedient Rastafarian -- he admits that he smokes pot frequently throughout the day but says it has never (or no longer) affects his performance and points to his 4.O GPA in advanced applied engineering. He says that his smoking is part of his rastafarain lifestyle and beliefs that guide his life spiritually. He offers to take a performance test or change jobs if the Er insists.
Jesus comes in. He admits that he does make some errors; mostly because he is preaching about the Lord to other employees and sometimes gets distracted. He also says that preaching is required by his fundamentalist christian beliefs. And he cannot stop and still adhere to his beliefs. The employer must offer him an accommodation that allows preaching.
You are the HR Director. Your companies relies on one big contract that will be up for review. Your Boss tells the whole management team he is worried the rising error rates will cost the company the contract and force layoffs.
What are you going to do?
