And while we're on the subject, Christmas wrapping paper is not suitable for sending items through the post. It's another thing I have mentioned before. It's not robust enough and will arrive in tatters. We may very well return to the subject of packaging later in the A to Z.
C is also for Chronic Understaffing, which appears to be the (deliberate?) policy of senior management. 10% of roles in our office are currently vacant and there is a moratorium on recruitment while we are in dispute (extending the moratorium that was in place over the summer). One aspect of the dispute is the sickness cover and the claim by management that sickness rates are very high. Their response to this 'situation' is to put staff under further stress by overworking everyone. I fail to see the logic. But then I am just a lowly postie.
(Disclaimer: this A to Z is not official Royal Mail advice, except by coincidence.)
Stay safe. Be kind. Plan ahead.
