I have a stock plan from my employer, which includes RSU vesting on certain dates through E-trade's services. Currently, E-trade has technical issues, which are preventing me (and some other employees in my company) from getting our RSUs vested, causing them to miss the agreed date of the vesting. The agreed date is precise and does not include a "within X business days" clause. Having in mind how fast the stock markets change, there will be a difference in the price of the stocks when they get vested. In the case where the price has dropped, does that classify as a loss or missed opportunity induced by their technical difficulties and is that something that can be pursued?
