The most practical solution for this reader's problem is already built into the spreadsheet they're using. Conditional formatting can highlight rows where column A contains "break" and column F exceeds 16:00, and it can scale to handle different aux codes and thresholds without requiring a single line of VBA or a pivot table. The trick is a formula-based rule, not a preset color scale.
Here is how it works. Select the entire data range, open conditional formatting, choose "New Rule," then "Use a formula to determine which cells to format." For the example given, the formula would be `=AND($A1="break", $F1>TIME(16,0,0))`. Apply that to the range, and every row where the aux is "break" and the duration surpasses 16 minutes will turn the color you choose. To add other aux codes, say, "lunch" or "training", you wrap the condition inside an OR: `=AND(OR($A1="break", $A1="lunch"), $F1>TIME(16,0,0))`. Each aux can even have its own duration threshold by nesting separate AND statements.
This is not a hack or a workaround. This is the intended use of conditional formatting in any modern spreadsheet application, including Excel and Google Sheets. The reader's promotion into management means they now own the data, not just the rows. Learning one formula-based rule replaces the need to manually scan hundreds of rows every shift. It also eliminates the risk of missing a violation because your eyes got tired at hour six.
The real takeaway here is that the barrier to solving this problem is not technical skill, it is knowing that the tool already expects you to ask it questions this way. The reader does not need to become an Excel expert. They need one pattern: `=AND(condition1, condition2)`. From that single building block, they can audit any combination of aux codes and durations, add new rules when the policy changes, and share the file with their team so everyone sees the same highlights. That is the difference between managing a process and just working inside it.
