I can't speak specifically on the latter part of your question. The issue for us is primarily around families who are posted and move around the country. It leads to spouses or partners not being able to find appropriate employment, and we all know that nowadays you need two incomes to live appropriately.
As spouses and partners move with their military members, they may not be able to find any job, or they may have to go to the great organization Tim Hortons and work there. We call it underemployment. It's the idea that perhaps as a medical professional they don't have the qualifications according to another province or territory, and they are underemployed.
