Just for a little clarification of the term "Scab," I always thought it refered to someone who "flew your planes" during a strike. Not someone just doing the job he/she was hired to do with his/her own company. Now, if they accepted to fly outside of their monthly max, to help the company out...then I see a bit of a problem.
Even Regional pilots during the AC strike didn't answere the phone on their days off, some may have been tempted, but we didn't hear about it afterward, so I assume not many, if any did.
