[or] My Company Has Asked Me To Cross A Picket Line And I Don’t Want To. I Am Not A Part Of The Union. What Happens If I Refuse?

I’ve done some research and from what I can tell, I’m protected by the NRLB from being fired for sympathy striking but that they could still fire me for “legitimate” reasons. Of note, I am a remote worker so there is no actual reason for me to be on site other than to be a scab and support the company. I have said I would work the shifts because I feel like I don’t have a choice but as someone who is staunchly pro labor, I am devastated. My worry is that I will get a mark on my record and be first up for layoffs whenever the next round inevitably comes if I refuse. Am I screwed?
