Because successful mobility largely depends on the accompanying family: a spouse giving up employment, children in a different school system and a couple far from relatives. Families informed of the consequences of their move can leave more confidently.
Individual discussions with an employee and their family remain confidential under professional secrecy. A business may fund a workshop or mediation; it is told only about participation, never the content of discussions.
Employee workshops before departure, HR training on family risks during mobility and family information: see Businesses and associations.
I work with businesses and welcoming associations as a trainer.
