Saga has confirmed that 100 of its employees are being made redundant.
The company, which caters for over-50s holidays and insurance, operates from offices off the Haine Road in Ramsgate and in Folkestone and Hastings.
The Ramsgate office has around 600 staff.
Saga has not confirmed which offices are affected by the redundancies.
A spokesman said: “We can confirm that the difficult decision has been taken this week to make around 100 employees redundant across the business.
“This process is being managed sensitively with all of Saga’s impacted employees. We are consulting with all those affected and until this process is complete we are unable to confirm the changes that will be made.
“Like many companies, we review our structure on a regular basis and in taking this action our objective is to make the business more efficient, customer focused and sustainable in the long term.
“We have made good progress this year against our strategic priorities, including the launch of a membership programme to reward our customers and the agreement to build a second new ship. The changes we have made this week will allow us to invest further in future growth.”
Saga has had a site in Ramsgate since 2003.
