You're asking me to prove a negative. Bosses at other companies have been caught locking employees in factories and physically preventing them from leaving.

Can I say for certain that this didn't happen at Id? No, but anyone making that claim ought to actually provide evidence that it happened at Id, not simple point to some other company that engaged in this behavior.

Aren't there laws already against that? It's happened before but is it common, do we have evidence that it is prevalent in Software Engineering?
