I have resigned from my position today after 21 months in my role. I do have some vested RSU that have a 2-year block (i.e. that can be exercised in November 2019). I have paid taxes on these RSUs. but I simply cannot exercise them until the block is lifted. Does a resignation triggers the block to be lifted, OR am I allowed to sell the RSUs in November, even though I will no longer be part of the company?
