Cisco is the largest maker of computer networking equipment. Over the 12 months that ended in July, Cisco earned $9.61 billion on revenue of $48.01 billion.

“None of the affected employees are represented by a union, nor do any have bumping rights applicable to the positions in question,” Cisco stated in the filing with the Employment Development Department.

When bumping rights do apply to companies’ positions, they typically allow employees with seniority to displace another employee, particularly in situations covered by collective bargaining agreements.

Although the tech sector has been robust, numerous job cuts have also occurred in the industry during 2017, including employee dismissals at Redwood City-based Oracle. A few weeks ago, Oracle disclosed plans to eliminate 900 jobs in Santa Clara.
