No Reasonable Alternative but to Leave

A couple may decide to change places of residence for personal reasons that are unrelated to the place of employment of the spouse or the individual living in a relationship of a conjugal nature. The couple may wish, for example, to move to the country or into the city. Whether this decision was made unilaterally by one person or was a joint decision made by the couple is of little importance1. What has to be decided, once the decision to move was made, is whether the decision of one person to accompany the other was justified. In determining this, one must take into consideration all the circumstances surrounding this move and ask whether, in this specific case, leaving employment was the only reasonable alternative2.
