Alton Towers says it may be forced to cut up to 190 jobs as a result of the ongoing effects of a rollercoaster crash that left five people seriously injured.
The theme park said visitor numbers have been down, particularly over its key summer months, following the "devastating incident" on the Smiler ride in June.
Two women had a leg amputated following the crash.
An Alton Towers spokesperson said: "Regretfully however, it may result in the loss of up to 190 salaried jobs across the resort."
Alton Towers embarked on a full review of its operations, following the crash.
"This was an incredibly difficult decision to make and it has not been taken lightly or easily," the company said earlier in the year.
"However, we believe that this reorganisation now, together with a continuous programme of capital investment, will not only ensure the resort's long-term growth, which is so vital to the local economy, but also protect the jobs of the bulk of its employees for the future."
