There has been a number of large corporation wanting ALL their employees to support gross immorality by the wearing of rainbow buttons, etc. Any company that is serious about making money will not get involved in contentious issues like abortion etc., but some businesses are not so serious I guess. I once saw a TV news show where everyone was expected to take part in a ceremony to a Pagan god. These people hate Christians. It is becoming more common for companies to violate the constitution and deprive people of their religious rights.

1. If it is a one day event or a training, call in sick that day. If it pops up out of nowhere, get sick all of the sudden. I came across bosses that got extremely angry at employees that really got very sick, even a person that vomited at work. But it has a lot less negatives than saying "This is stupid." It is true you are sick, sick of the BS. Any normal person would be sickened by the pride crowd.

2. Have an in-demand special job skill. There is a pattern to this that it is usually unskilled workers that have to go through this. Notice the workers fired at Krogers are low level, unskilled?

3. Quit. There is always another job out there. Probably be better off asking for the day off, though. Long term the Christians should get out of the evil company anyway.

4. Talk to your boss if the boss is someone reasonable. Ask for a job in the back room. You know your boss. The boss might say, "Yes, OK, you can skip it since this is your belief."

5. Sue. For most though, this is unrealistic. If you sue, for practical purposes, you will not be able to work there anymore. Make sure you get documentation of your firing. Record names of anyone involved. Email a few people in the company including every co-worker about what happened. Maybe one will say "Yeah, I was there, you deserved it because you are a bigot." Email/text all supervisors in separate emails or Bcc. Employers will often fire people then claim they never fired the person. Write down a statement that day and get it notarized. Find a law firm that specializes in religious freedom. A local law firm probably won't touch it.

6. Ask for an accommodation like handicapped people. Say "I am happy to do whatever, but I need an accommodation for this." Perhaps ask human resources. The manager or even regional manager might be violating corporate policy. "Accommodation" is a magic word.

7. There is a remote chance your church might help you, but it is unlikely. An employer might be intimidated by a phone call to Public Relations by a prominent representative of a large church. Even if you happen to belong a to large church, I would say there is a 98% chance they will do nothing to help you beyond telling you about the twice a month free food pantry. Did your church ever help any member in the past in any substantial way? Probably not. This is the reason companies get away with this to begin with.

The number one problem, beyond any, is that most of your fellow Christian will not care. I guarantee that over 99% of Christians that show up to Church on Sunday, that read about what the supermarket did, will continue to buy from Kroger as often as they did before. Never forget that. There is .01% that will care, so see, you would have some support from some fellow Christians.

Here are some tips when a company wants you to deny your religion: https://www.workplacefairness.org/religious-discrimination

QuoteKroger, one of the country's largest supermarket chains, is being sued in federal court after two former employees claimed they were wrongfully terminated for refusing to wear an apron with a rainbow symbol.
The ex-employees, who identify as Christian, cited religious objections

BLM is a more pressing issue. Like I said, Starbucks has BLM embedded into their computer software, so you can't delete or change the screensaver. What about those who work at Starbucks who are forced to take part of the racist Marxism?

Going to religion is not always an option since most churches are supporting the BLM embedded into a rainbow flag.

One option that I left out is if the person is in a union. I saw in the past unions helped workers in situations of accusations of racism. Both teacher and police unions. This is the reason Antifa hate unions. Generally though, if there is a union you probably won't end up in a situation what happened at Krogers to begin with. Never heard of a unionized person having problems with religious accommodations. It might happen, it is just I can't find examples.

Talk to a lawyer and find out what your rights are.
Then, talk to HR and suggest this is against your conscience and could be considered harassment to be forced to participate in something OUTSIDE your job description.

We have a family of Lawyers for cousins - they have offered free advice from time to time.
Their standard line has been, "Just SAY what you want-think and don't try to couch it in legalize."

I, as a born again Christian, was hired to work at a Roman Catholic Seminary, as a maintenance man.
I had everything they wanted in experience, except I was not Catholic.  In fact, I had written Gospel Tracts, targeting Catholics (was not brought up in the interview..., nor was the fact that I had used a booklet written by one of the professors there.)

Not once in 6 1/2 years, did I participate in a Mass, or so much as sit in a pew.  Everyone KNEW I was a "Protestant" - they were happy to have a little diversity... I guess... but I also worked HARD and when complimented, I'd respond, "probably that Protestant work ethic..."   ALL of my annual work reviews were good, I saved them money... essentially, I was "harmless" to them, always polite, "Yes Sir" instead of "Father..."  Sometimes a PC place is really a great place to work and not be constantly harassed.

There was one guy, who was constantly trying to poison the work environment - or kill me - eventually, I decided it was time to leave on a good note, than not.   Before I left, I got my supervisor to write a letter of reference, and got a copy of my personnel file - I still have both, 25yrs later.   The guy went into overdrive after I was gone, got garbage inserted into my personnel file, and talked my supervisor into giving me bad references - cost me a job at a big insurance firm... who told me what he said.  I called my former supervisor and read him the letter he wrote, and was very clear, if he cost me another job, I would SUE him, that he had better stick to the letter he signed, period.  He did from then on.  I was told this by an old friend, who worked at a place for decades, a good guy, who got a new boss who hated him.   15years of great reviews - suddenly ruined by the new guy, a total jerk... ALWAYS get letters of reference from those who *like* you, while you/they are still employed, on company letterhead - it's your insurance policy.

If you're like most people, you've had good bosses, and bad bosses - don't take the good guys for granted, THANK THEM OFTEN.  They're more likely to go-to-bat for you, because they realize you actually appreciate them.  I see my current boss 2x a month - the rest of the time, we're on-our-own... he says, "You guys run on auto-pilot, I never have to worry about you, check up on you."  We THANK him for trusting us, and giving us flexibility in getting things done.  We've never been questioned on our "judgement", and do not take advantage of our lack of direct supervision.

HR is your greatest ENEMY at work.  Most of them are LIBERALS who couldn't hold a real job, but feel the need to lord over the rest of us, like we're complete idiots.   HR comes up with the wildest, craziest, dumb ideas - couched in "inclusive" and "team" language.   My policy is "get my work done, then go help others" - "I am NOT my co-worker's boss, I will NOT inspect their work - that is the job of the manager, not me." - "If the manager can't trust you, they should either fire you, or learn how to trust people".  But, HR trusts nobody, and is more likely to get the company SUED than someone like Gropin' Joe Biden.  The only people HR fears are the EEOC and Lawyers... they're not even afraid of the CEO, 'cause they think they've got all the dirt on them an everyone else in those files.  So, before you talk to HR, and give them the, "This is stressing me out, and hurting my productivity, agonizing over this policy that was not in my job description..." - bone up on your rights.  Record EVERYTHING, emails, audio (if you can, so you can quote them verbatim.)

And trust me... I've been burned a LOT of times as a Christian... it goes with the territory, this world is not my home, I'm just a passin' through...  Don't get bitter, Trust the Lord, be THANKFUL in everything, and whenever you can, tell people how "Good God has been to you.", no matter what the circumstances, "God has been VERY good to me!" 

"What to do if your employer wants you to deny Christ?" It's pretty obvious to me, QUIT!
