It's not about low performers, but workers who complain about mistreatment. There is usually nothing preventing unionized companies for offering higher pay for high performers, but sometimes they use the union agreements (which ask for wage adjustments well below inflation the inflation rate at the moment) as an excuse not to offer higher wages. A game company might not like unions because it would harder to retaliate against workers protesting against illegal "crunch" time. Just an example.
