About six weeks later, on Sept. 3, Gov. M. Jodi Rell announced the state was offering Pratt $100 million in incentives — $20 million a year for five years — to change course and keep the Cheshire plant and East Hartford business unit open.

But the company’s decision last week to reject that offer — several years after Bayer Corp. in 2006 shunned a $60 million state incentive package and moved its U.S. headquarters from West Haven to New Jersey — has some questioning whether the state does enough to retain businesses.

Tom Mayes, vice president of Pratt & Whitney Commercial Engine & Global Services, in announcing the company’s decision Monday, said the state “made a generous and creative proposal in an unprecedented effort to keep jobs in the state.”

The incentives, however, did not address the main issues the company faces, he said — volume loss amid a declining aerospace market and labor costs. The impacted jobs will be moved to Georgia, Singapore and Japan.
