In fact, there are two problems. The first is the precariousness that results from the difficulty of holding a job on a continuous basis. We need stability in the supply of contracts. In a majority of cases, the various orders of government prefer to advertise on an ad hoc basis, rather than planning to stagger workforce supply and demand over 12 months of the year. That means that construction peaks and then supply falls. At that point, people find themselves unemployed and are looking for another job. So there is strong competition and that is when they get injured, because they are so anxious to prove they are the most productive, so they will get called back to work on the next project when the supply of jobs falls.
So governments, which are major sources of construction contracts, should be planning the demand for labour, to make sure people are offered a minimum number of jobs so they have something to eat year-round.
The second thing is that employment insurance has to be reformed, obviously.
