My last company's retention package after their [bad] acquisition had this vesting schedule. The company knew damn well that most people would leave or be forced out before the 3rd year, and that's exactly what happened. This sort of vesting is the most employee-unfriendly bullshit out there. If I was made an offer with this sort of schedule I would immediately decline and look elsewhere.
