In fact, under the cover of a student assignment, they're filling classified positions. To add to my colleague's remarks, I'd say that all the agencies may have problems with implementation of the FSWEP, since there's no monitoring. For example, I heard that, at Statistics Canada, they hadn't yet paid students for hours worked this past summer.
In that case as well, they can only complain, but if the administration doesn't pay them, they won't have any recourse. They can't even ask the Public Service Commission to investigate the situation.
