International assignment experience is valuable. This is especially true when it comes to repatriation.
They wonder if the assignment hurt their career. This, which costs little or nothing, can create an additional level of support from the organization and help ensure continued, strong relationships upon repatriation.
Compounding this is the pressure on a trailing spouse to restart his or her career and quickly find appropriate employment. Ability to accelerate the transfer of knowledge between countries.
Then they are surprised when that person leaves. Post-assignment— it is as though top management is suffering from amnesia. Keep in touch with home country friends and co-workers. What is worse is that these figures have been consistent for the past 30 plus years.
