<human>: My father works for a small company and a while ago it was bought out by a Scientologist couple. 

He's been telling me that they have been threatening his job if he doesn't attend their daily/weekly scientology meetings within the office. He attended one out of fear of loosing his job, and all they did was push him to convert. Since that he told them to leave him out of it. But they still keep threatening his job, and making it harder for him to get things done because he refuses to attend/convert. He says he's too close to retirement to rock the boat more then trolling them here and there. Annoyed I decided to see what rights he has, and I found that [Title VII of the Civil Rights Act of 1964] doesn't cover him because they do not employ more than 15 people. So, what gives?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Title VII of the Civil Rights act only covers companies of 15+ employees. This includes discrimination based on race, color, religion, sex, or national origin. Why?
