The bank recently told 58 of its IT workers they would be transferred to HCL, a big Indian outsourcing company.
As India's Economic Times reported, the bank, Switzerland's second-largest, told the 58 that their terms and conditions would remain the same for another 12 months.
They would be able to remain in Zurich for the same amount of time.
"Credit Suisse has been working with external providers worldwide for many years, as is common in the industry," the spokeswoman said. "HCL has an excellent reputation in the market and was selected as a partner following careful evaluation."
Credit Suisse has 17,020 employees in Switzerland and aims to cut 1600 staff by the end of 2018.
