The East Pilots crossed the IAM Mechanic and Related picket line in 1992, I filed many a grievance during the 30 day cooling off period when pilots were cleaning thru flights as we were short handed, they cleaned planes during the strike and made a sweetheart deal with the company for all pilots to get paid during the strike if they crossed the picket line, the company grounded all the DC9s, MD80s, F28s, and 737-200s, yet all the pilots got paid.
I would think Jack London would agree you fit the definition of his poem.
