Requirement to cross picket line as a non-union employee? One of the unions at my workplace has gone on strike. Accordingly, workers from all other unions have refused to cross the picket line in support. I am one of a few non-union employees at my workplace, and in fact, I am not even paid by this employer. I work for an external organization which has an office inside the buildings of this major employer, and my paycheque also comes from this external organization.  I was told by my organization that I am required to go to work despite the strike. However, I feel very uncomfortable about crossing the picket line! 

I'm confused about whether the picketers will be mad at me if I cross! Is it ever ok to cross a picket line?  I was told I could get reprimanded if I do not go to work. I'm just super confused and would hugely appreciate any advice! 

ETA: I do support the strike and the workers. But I also don't want to get fired!
