Every week the company posts the operating schedule for the following week. We use to post these on our site back when we were all working mandatory OT, as they contained that schedule too.
Members are encouraged to visit the company site for updated info and changes to the shift schedules.
The schedules are located on the CAMI Employee page at the very bottom, under the job postings section.
