How are Continuing Education Hours credited for Open Shop Time?
Members can earn time towards their 24 hours for the Continuing Education Reimbursement Check during Open Weld Shop hours. To receive credit, members must use the sign in sheets to record their name, their start time, and end time. If the member does not sign in and out, they will not receive credit. A maximum of 16 hours of Open Weld Shop time (combined with other “Open” Labs and approved Outside Education classes) can be credited towards the 24 hours needed.
