In the context of the current situation where many pilots (and others) find themselves unemployed or under-employed, I think there will be many crew members in the future who find themselves under considerable personal or financial stress. Inevitably this must have some effect on their performance at work.
Now more than ever is when employers (especially the large ones where cuts have been deep and the notification quite impersonal) need to be bolstering their employee assistance programs. Surely in such times the temptation will be to cut back on what the employer may regard as "non-essential" costs, but the need may be greater than ever.
