SeaWorld Entertainment Inc. is eliminating 320 jobs across its 12-park company.
Company officials said Tuesday in a statement that the goal of the restructuring is to eliminate costs and improve the company's operations.
The job eliminations involve both salaried and hourly workers.
Company officials say the changes will position the company for long-term success.
SeaWorld's attendance and revenue have suffered in the face of a campaign by animal rights activists.
Earlier this year, the company announced it was ending its orca breeding program and stopping its traditional killer whale shows.
The company has parks in Florida, Texas, California, Pennsylvania and Virginia.
