It's not a frivolous problem as job stress can lead to poor health and even injury.
Job stress is different.
Stress is what happens when demands cannot be met, when there's no time for relaxation, and when there's no sense of accomplishment. Sometimes we don't have much choice. A particular job may simply be too demanding or beyond our capabilities. If this is the case, we may need to step back and ask if the compensation we get is worth the stress, if we have any alternatives, and how we might successfully get ourselves moving towards the direction of those alternatives. We may also need to ask if some of the stress we feel is self-induced.
