Rogers Communications is preparing to lay off up to 300 employees, and began notifying affected workers Wednesday.

Rogers is Canada’s largest telecommunications company, providing service to more than 9 million mobile phone customers, millions of cable and broadband subscribers, and has ownership stakes in some of the country’s largest broadcast outlets and print publications.

“This is a very difficult decision, obviously,” Patricia Trott, Rogers’ director of public affairs, told the Toronto Star. “We don’t make these decisions lightly but we really feel we’re positioning ourselves well to maintain our leadership going forward.

Trott confirmed most of the layoffs would come from management and head office positions.  The company has been studying ways to increase operating efficiency.
