I would not say it's related to a particular case. It's taking a look at the EI program and its objectives to achieve an effective and efficient labour market. Along with that is looking at measures within the program that would create an incentive to return to work, and while a variety of approaches have been tested over a 12-year period, this is one that has been found to have a greater incentive, in particular because it offers a sustained incentive to work. In other words, if you work for one day, you are earning some additional income. If you work for a second day or if you work for a third day, you continue to be earning greater income overall.
Some of the approaches in the past have had a threshold beyond which those incentives disappear. Someone who worked beyond one day during the week would complain that they were working for nothing, because the EI program would be reducing their benefits by $1 for each dollar of earnings. This is a different approach, where it is 50ยข on the dollar.
