  Highly mobile  employees might face health problems but their well-being is also affected by less visible factors such as  stress, financial, and work-related issues. Demotivation, family issues and  ultimately failed assignments can be a manifestation of these issues. Organisations support their mobile employees  with comprehensive reward and relocation packages but sometimes fail to take a  holistic approach to employee well-being.
How can we design a support program, enlist the support of management, and  secure the participation of the assignees themselves?
Defining wellbeing
  Employee wellbeing has  a broad definition that encompass more than just health issues:
Physical wellbeing: lack of physical activities, sleep  deprivation, poor nutrition, life in difficult and polluted environment lead to  chronic health problem. The problem is not so much tackling a given disease  (through insurance) as avoiding a slow erosion of the physical condition of  assignees over time. The objective is to anticipate health problems rather than  just pay for medical costs.
Social wellbeing: integration in the host locations and create a  sense of connection with a wider community at work and in the daily life is a  condition for employees to thrive in a new location. Companies address culture  clash through Cultural training but it takes more effort to integrate  individuals in foreign teams and build support groups to provided practical  information but also to break the sense of isolation.
Financial wellbeing: short-term assignment-related issues are  generally addressed via comprehensive relocation packages. But long-term consequences  are not always anticipated: pension, savings (currencies). The question of pay  need to link with Career: is not so much about guaranteeing a job as maintaining  employability: skills and network developed. Being cut from what’s important  could pose problem for the future. Accompanying spouse, the huge risk and difficulties  of rejoining the workforce.
Mental/emotional wellbeing: Emotional wellbeing is influenced by the  other wellbeing dimensions and ultimately drives performance and satisfaction.  It can be impacted further by assignment related problems (workload,  expectations, family issues.) 

Mobility is about more than just one employee
 While in a local  context companies have a duty of care for their employees, in an international  mobility context, the responsibility extents to family members who are also  relocated abroad. Beyond strict duty of care, family wellbeing issues reverberate  on emotional state and performance of the employees. While Companies are reluctant  to get involve in private issues but they might be creating new difficulties by  requested employees and their families to move abroad. The willingness of the  employees to accept moves doesn’t exonerate employers from their duty of care.
Spouse: accompanying spouses  to interrupt their careers. Children: school disruption and making long-term  decision about their school curriculum. 
Invisible problems:  not all assignees are equal when moving to a host location. Women and  minorities can face discrimination or additional challenges in some countries.  This is true for the employee but also for the family. The issues might be  unreported: invisible minorities: the employee can avoid discrimination but a  family member might face problems.
 The business case
While Duty of  care should be in itself a sufficient justification, there are business  benefits to proactively support wellbeing of employees.
Managing costs: Proactively support the  wellbeing of employees is good for the business:  productivity issues, low satisfaction and  failed assignments have a cost.
Reputation  risks: The perception that a  company doesn’t take care of its employees is likely to damage its employer’s  branding. 
Cascading  impact: stressed manager can  negatively impact the performance of their teams, negative expats can become a  negative role model and disrupt operations in the host countries and also become  negative role models – i.e., complaining  about their experience abroad and portraying mobility in the companies as a  risk for employees.
Best practices
A different  mindset is needed: Retention is  not driven purely by pay. Organizations need to put more emphasis on the needs  of the whole person (e.g. community, purpose, job satisfaction) and also take  into account the need of the family. Wellbeing is an important component of the  employee value proposition. Build a business case to show the cost of lack of  wellbeing and the business benefits of support and prevention programs.
Foster open communication: give employee the possibility to talk about  issues without being penalized. In the context of international assignments,  many candidates prefer to take a chance rather than miss a career opportunity.  It should be clear to them and their managers than voicing concern is OK and  encouraged. Message form the top: employees should not have to choose between  their health and their jobs.
Define  who is in charge: supporting  employee wellbeing requires collaboration between all stakeholders and cannot  be driven solely by the HR team. The mobility team, home and host HR  teams and line management need to have clear roles and responsibilities to  inform and support mobile employees.   Training might be required, especially for receiving business units who  are not familiar with expatriates. Finally, the employees themselves  need to understand what is expected from them and received the information and  tools needed to make educated choices.
Incentivize best practices: Asking  managers to focus exclusively on financial objectives for managers could  deteriorate team work and employee wellbeing. If employee wellbeing is just “a  nice to have” without impact on reward and recognition, managers have little  incentive to adopt best practices. Teamwork, inclusion, coaching and more  generally supporting employees need to be included in performance evaluation  criteria. Organizations should also consider rewarding employees willing to enrol  in optional prevention and wellbeing programs.
Managing  flexibility: Flexibility can enhance wellbeing when applied  selectively to allow for a better work-life balance or to let specific employee  groups choose what they need. Poorly implemented it could lead to additional stress  for employees who don‘t necessarily have all the information and support to  make educated choices. In hardship locations excessive policy flexibility can  lead to duty of care issues. Elements that are essential for the wellbeing of  employees and their families should not be made flexible and optional.
Connect  with diversity and inclusion teams: There is a  connection between mobility, diversity and wellbeing issues. D&I and Mobility team need to work together to  ensure that mobile employee benefits from inclusion initiatives and that  mobility is fostering diversity. Lack of inclusion can create wellbeing issues.  Support groups and local networks can help with isolation and practical issues.
