Sikorsky will cut about 540 employees from its global workforce, which is about 3 percent.
Officials from the Stratford-based company informed employees in Connecticut and Poland on Thursday about the cuts.
Eligible union members in Connecticut have been offered a voluntary separation package, the company said in a statement.
“We will not know how many involuntary reductions may be necessary until the results of that offer are known,” the company statement said.
Sikorsky officials said the company has experienced strong growth, sales have increased nearly 40 percent since 2007 and they’ve been able to expand the workforce by nearly 59 percent since then, but these growth rates aren’t sustainable.
