SAG-AFTRA, the union which looks after voice actors (among loads of other jobs), is mulling over whether to strike in order to obtain better conditions for its members.
Specifically, they want it enshrined in contacts that there's better protection and pay for when a role requires physically demanding voice work (such as repeated loud screams), clearer definition between the roles of voice actors and motion-capture actors (the former is often expected to do the latter unexpectedly) and performance bonuses should a game sell over 2 million copies.
Why a strike? The union and video game publishers met first in February and then in June to try and sort out a new contract for voice actors, and were unable to come to an agreement. So a vote is going down early next month, and if over 75% of members agree, then all union members working on video games will go on strike.
