The move by Capita has been put down to the falling number of calls to the teams that handle calls on behalf of PC World and Currys.
However, a spokeperson for the retail group told PC Retail "we don't anticipate customer service levels to be harmed by this announcement".
The cuts will affect two of Captia call centres. Its Sheffield office is expected to lose 26 operations team leaders, while a further ten have are earmarked at its centre in Nottingham. Six support staff have also been warned that their jobs are at risk.
