Yes, but what immediately comes to mind are the eligibility criteria. The current threshold is 420 hours, and we'd like that to continue. The threshold can be calculated in hours or weeks.
In addition, individuals are disqualified for voluntary leaving because they don't have proof that they were available for work or because they didn't take steps to look for work. It seems to me that the question whether a person is available depends on the circumstances of the workplace. I'm thinking, for example, of seasonal workers and construction workers.
Workers are often disqualified from receiving employment insurance benefits in voluntary leaving cases. However, in some workplaces, some departures seem to be voluntary, whereas they're related to employment circumstances. Once again, I'm thinking of the construction industry and seasonal jobs, which give rise to voluntary leaving. That would be a response to go after.
