The company has become stingier over the years. Various job roles and departments used to receive certain bonuses or commissions based on their production targets, and now some of those bonuses have been taken away. Remaining bonuses have become harder to obtain because management has raised the target that needs to be hit in order to earn it. When you take away incentives for people to perform well (or make it more difficult to obtain), then people will lose desire to perform well. Quality will go down, and both employee and customer satisfaction will be hurt. It changes the environment from one in which production employees are motivated to do their best and excel, to one where a large amount of people have mentally given up and just do enough to keep their job.
