What is an employee blackout?

[i_call_solo]

It's a policy that prevents employees that have been awarded shares or options to immediately sell their shares once the company goes public to avoid it flooding the market and lowering the price.

When employees are not allowed to sell shares. I think in the case of Palantir though they allowed them to sell up to 20% of their shares.
