SAG-AFTRA threatened a strike last year after its previous agreement expired, and negotiations with indie game producers for a new one broke down. Actor and alpha geek Wil Wheaton unwittingly became the poster boy for the cause after tweeting support for the union and explaining in a post why actors need a new deal. Noting that producers have ignored concerns about tough vocal sessions, he said that afterwards, "your voice is wrecked .. and over years and years of this, it's going to build up into serious and permanent damage."

Your voice is wrecked .. and over years and years of this, it's going to build up into serious and permanent damage.

Producers and critics, however, argue that the indie game industry works on tiny margins, so it can't afford residual payments. They add that developers and programmers work much longer hours than voice actors.

The union failed to carry out its strike threat, and the situation reached an impasse this summer. The contract that voice actors are proposing is essentially the same one that producers rejected before. As a result, Deadline notes, few game producers are expected to sign the deal.

SAG-AFTRA does have a plan "B," however -- it is saying that vocal stress is a workplace safety issue and has also made a claim before the Occupational Safety and Health Administration (OSHA). "We'd rather not have to petition for new regulations," it said in a statement, "but since the videogame employers are unwilling to address vocal stress in negotiations in a real way, we are investigating this further to protect the voices of our members."
