If I understand you correctly, you might be speaking about the final point I was making in my comments at the outset. This has been a continuing problem. If someone is on parental leave and then later on needs to go on regular benefits, in this case because of a summer lay-off, they may find some work over the summer, but if they don't, then they will be on EI. If they have been on parental leave during the year and exhausted their entitlements, and did not get enough hours to requalify, then they don't get the regular lay-off benefits that another colleague might, and the reverse happens too.
