This should not matter. Traditional portfolio theory suggests that investing where you work is not a good idea (diversification, familiarity bias and so on). Or you can look at it another way; if you are offered two options:
1. $19K now (approx 24c minus 5c) or
2. $0K now but a very highly likelihood (not 100%; for argument sake, say 90%) chance of getting say $35K in two weeks.

In my view, it makes sense for employees to sell at least some, because the stake is much higher for them. They will not have the $19K and future of their jobs uncertain.
