job rotation

[bosun]

Hello! I am not sure if the following sentences sound natural . Please let me have your commetns.

Currently I'm mainly responsible for the operation of security system, PC Plus and Security Portal, in MC Lab. My boss asked me to get in touch with you because we have job rotation, so I will be in charge of the security system instead of Mr. Han. I look forward to work closely with you in the future.
