Health and Human Services Secretary Kathleen Sebelius should visit SeaWorld this weekend, said Sen. Marco Rubio, R-Fla., so she can talk to employees having their hours cut due to Obamacare.

"I want to make sure you are aware that just across town from where you will be speaking [Friday] is SeaWorld, a theme park whose parent company — SeaWorld Entertainment Inc. — became the latest employer this week to announce that it will cut the hours of its part-time employees to avoid the potentially devastating costs of Obamacare," Rubio wrote to Sebelius in a Tuesday letter.

SeaWorld announced that it would allow part-time employees to work no more than 28 hours per week, rather than the 32 hours previously permitted. The decision was based on an Obamacare regulation written by Sebelius' department.

Rubio isn't the only person blaming Obamacare for the new policy. "There is no other reason to change your cap from 32 hours to 28," Duncan Dickinson, a former human resources official at Walt Disney World, told the Orlando Sentinel.

An Obamacare regulation requires companies to provide insurance coverage to employees who work more than 30 hours a week.

"[Obamacare] is devastating to people trying to provide for their families because businesses are forced to delay new hires, reduce workers’ hours or have to lay them off," Rubio wrote in an Aug. 23, 2013, opinion column.
