There are five specific factors that I referred to. One factor is whether or not sufficient work for the individuals will be available in the long haul, not just for the next five to ten years. People are very self-conscious about this. There are the financial barriers in terms of the cost of apprenticeship or whether there will be sufficient income, but again this is perception-based. Another factor is they're sometimes receiving better and more competitive job offers elsewhere that you wouldn't expect, that may not be trade related, but the contractor who employs them has certain specific needs for individuals who are generalists to develop those skills due to a particular project. Then there's the employer participation in terms of supporting the apprenticeship. Sometimes some of the barriers that are fairly unique are essential skills needs where individuals have numeracy and literacy challenges that need to be overcome.
I would leave it at that for now.
