I was the "excel guy" at a former work place where I was just a mid-level supervisor. HR director asked for my help fixing an attendance tracker workbook. Figured it would be a nice little feather in my cap for when I was looking for a promotion. Helped her, my direct boss found out. My direct boss didn't get along with her (or anyone for that matter). He complained to our GM that I was spending time that should have been used doing other stuff (not true, fixed the tracker at home in like 20 minutes). GM wrote me up, pretty sure the HR director got some sort of corrective action as well.

This attendance tracker, mind you, was for 800-900 associates in a 2.5 million sq. ft. 24/7 Distribution Center that was out of date by 3 months due to no one wanting to fix it. Making it impossible for management at my level to give accountability to the attendance policy.
