Instructions provided ensure that marker line symbols stay upright in a map by converting the symbology to Cartographic Representations. This does not affect corresponding labels even if they are rotated.

An option for cartographic representations allows the marker line symbols to not be angled or rotated:
The features that are being symbolized must be in a geodatabase before proceeding. This is because Cartographic Representations can only be created for geodatabase feature classes.

- Select 'Convert Symbology to Representation'.
- Name the representation using the default settings, click 'Add new layer to map symbolized with this representation' to uncheck it, and then click Convert.
- Right-click on the layer and navigate to Properties > Symbology.
- Under Representation, click the representation created in Step 3.
- Click the Marker Symbol tab, uncheck the box 'Angle to Line' in the Along line section, and click OK.
