That could work not just in the private sector, but also in the public sector.
I read a Department of Canadian Heritage report on the efforts being made to promote the use of both official languages. According to the report, the department had set up an employee exchange program, so an employee working in an English-speaking region could go on an exchange and switch jobs with an employee at the same level working in a French-speaking region. I found that wonderful. When I read the next page, I learned that the department had sent two employees on an exchange. It's a shame that the scale of the program is so small. People don't realize what an impact a wider-reaching program could have.
Indeed, I believe young public servants should have the opportunity to incorporate these kinds of experiences when carving out their careers.
