Hersheypark in Pennsylvaniacould be forced to close this summer amid a dispute between the site’s operators and union employees, according to a report. ​

The amusement park is scheduled to open seven days a week starting May 21 in a shift from its weekend-only operation before the summer, despite a looming vote among employees about whether to go on strike. ​

Over 200 union maintenance employees at Hersheypark, The Hotel Hershey and Giant Center rejected a contract offer from Hershey Entertainment & Resorts on May 7, according to Inside the Magic. The park’s operators described the proposal as their “last, best and final” offer.​

Over a three-day period this week, employees will vote on whether to strike after rejecting the offer, which is the third from the park’s operators. A strike could close the park just in time for the start of the busy summer season when families head on vacation.

​The list of employees considering going on strike includes ride mechanics, electricians, plumbers, welders, painters, machinists, utilities technicians, carpenters, garage auto mechanics and sign artists. ​

In mid-March, the union and Hershey Entertainment & Resorts agreed to extend a former contract for 60 days to allow for continued negotiations. ​

According to Inside the Magic, union workers are seeking fair wage increases, more affordable care plans and higher pay premiums for less-desirable shifts. The union has also said that it will reject new contract offers that lower professional standards, devalue skilled trades or open the door to lower wages in maintenance roles in the future. ​

The Independent has contacted Hershey Entertainment & Resorts for comment about the possible strike.

Hersheypark, located 15 miles east of Harrisburg, is the largest amusement park in Pennsylvania. Founded in 1906, the 121-acre site boasts more than 70 rides, a water park with 17 water attractions and an 11-acre North American Wildlife Park, according to Hersheypark’s website. ​

It’s named for and themed in conjunction with the popular candy company.

However, a different park in the Keystone State was named as the top amusement park in the U.S. on TripAdvisor’s Best of the Best list. ​

It was Knoebels Amusement Resort in Elysburg, 42 miles north-northeast of Harrisburg, that topped the list. In doing so, the little-known park was ranked higher than Dollywood, Disney World’s Magic Kingdom, Disney’s Hollywood Studios and Universal Islands of Adventure that also made the top 5. ​

“It’s got it all: roller coasters, kid-friendly rides (bumper cars, a haunted mansion), swimming, camping, a mining museum, and even a championship 18-hole golf course,” TripAdvisor wrote. “The accommodating staff, clean facilities, and fun attractions make for a memorable family-friendly visit.”​

Knoebels is the U.S.’s largest free-admission park, although tickets for individual rides cost a fee. ​
