Again, you don't get it at all.
I will be waisting[sic] my time to try to explain to you how childish this statement is. Companies do have incentive to not just demoralize their work force for no reason, but they also have to answer to the shareholders for future profits, not past profits. If they believe they are not going have the same revenue because of lack of demand for their service, the managers must reduce costs. In this case, unused pilot labor costs are probably quite costly. I agree with you that if they continuously furlough and recall, it may eventually cause pilots to stop applying to FedEx because of lack of job security. But, I would venture a guess that even if they furloughed 1000 people today and opened up their application online at the same time, they would receive thousands of applications. So, I think that they are not currently concerned about the supply of labor. They are concerned with the bottom line because that is why a business exists.
I'll say it again, companies do not exist to provide jobs. Companies exist to make a profit. The executives at your company are paid to make a profit. Creating jobs is a fortunate byproduct of the process.
So, if the managers at FedEx believe that they will not make enough money to utilize their pilot labor enough to keep them off of furlough, they have a fudiciary responsibility to the shareholders to furlough. Kind of ironic if you were a pilot there and a shareholder.
Nobody wants to see anybody cut jobs, but let's be grownups about the process. There is no evil conspiracy to ruin your life as a pilot by some evil manager cult. Poorly or well, the managers of companies are trying to keep their companies profitable on good and bad years. Looks like people think this is going to be a pretty rough one.
