Final answer:
Unexpected loss of employment is a significant life change stressor that causes acute stress with potential chronic effects, leading to financial strain, decreased self-worth, and adverse impacts on mental and physical health.
Step-by-step explanation:
An event such as unexpected loss of employment would be considered a significant life change stressor. Unemployment can be a traumatic life experience, causing financial stress and necessitating painful adjustments in one's life. The uncertainty of not knowing when the next paycheck will come, the depletion of savings, selling possessions, or moving to afford living expenses contribute to the overall stress. This can also lead to a decrease in self-worth, impact family relationships, and affect mental and physical health. It is an acute stressor that can have chronic effects if the unemployment period extends over time.
