Having supervised a workplace similar to yours, it's very easy to get in the flow of things when you're short staffed. You are doing a great job under the circumstances and you know it because you feel good about what you're getting accomplished today.
Sometimes when I'm being efficient, my employees tell me I'm not being sensitive. I think I pride myself on getting the job done in good timing and don't realize how my tone changes when I'm being efficient.
So, if you get through the day with a 95% success rate, I think that's fabulous!! Give yourself kudos for being able to handle the situation and just imagine if others in your office were under the same kind of stress you are today. It's not easy working with patients and other staff members.
Might I suggest a healthy serving of chocolate??
By the way, I have a cockatiel named Fiona. Love that name!
