Catholics being forced to go to services in a Kingdom Hall, where they will hear such things as:
"(2) WE ABHOR Christendom's adherence to Babylonish teachings, notably those of a triune god, the human soul's immortality, eternal torment in hell, a fiery purgatory, and worship of images--such as the Madonna and the cross...
(4) WE ABHOR Christendom's failure to heed Jesus' messages to the seven congregations at Revelation chapters 2 and 3 in such matters as sectarianism, idolatry, fornication, the Jezebel influence, lukewarmness, and lack of tachfulness."
[Watchtower April 15, 1989 page 18]
"...We must hate in the the truest sense, which is to regard with extreme and active aversion, to consider as loathsome, odious, filthy, to detest. Surely any haters of God are not fit to live on this beautiful earth...
...Do we not hate those who hate God? We cannot love thise hateful enemies, for they are fit only for destruction..."
[Watchtower October 1, 1952 pages 599 and 600]
How could this not be "hostile work environment?"
Religious Discrimination & Harassment
It is illegal to harass a person because of his or her religion.
Harassment can include, for example, offensive remarks about a person’s religious beliefs or practices. Although the law doesn’t prohibit simple teasing, offhand comments, or isolated incidents that aren’t very serious, harassment is illegal when it is so frequent or severe that it creates a hostile or offensive work environment or when it results in an adverse employment decision (such as the victim being fired or demoted).
The harasser can be the victim's supervisor, a supervisor in another area, a co-worker, or someone who is not an employee of the employer, such as a client or customer.
