Is it legal for a manager at work to preach his religion to employees at the work place?

it unethical to do so if it is during work hours and interupting the work

Of course it is. It's not legal to discriminate based on religion; but he is free to try and convert you heathens as long as he is not fostering a hostile work environment. You are free to complain to HR or look for a less denominational workplace

Advice? Tell him you are a reformed Druid, and thank him very much for his interest and concern; and if you want to consider switching to a non-holy tree religion, you'll get back to him.

it is not unlawful no longer count the way you look at it. although, maximum if no longer all agencies discourage this style of verbal substitute. whether it particularly is transforming into a topic for you I propose that first you handle him. enable him understand which you value his perspectives on his religious ideals although that it particularly is making you uncomfortable. optimistically this could help the subject. If that doesn't artwork then communicate along with his supervisor approximately it and that could desire to repair the subject. If no longer HR is often an determination...

Unfortunately, yes, it is. You can go to Human Resources and complain about it, and say that it's interfering with your work, especially if he's not your manager.

You might ask him to quit trying to convert you, sometimes this will work, sometimes it just makes the "preachers" more determined to Spread The Word.

Personally, I'd try to get another job, even in this economy.
