Text not clear when switching from Open Street Maps to Imagery basemap

[NancyStaton]

When I switch to the Imagery basemap my text is hard to read. I made the imagery layer more transparent but then it starts getting difficult to see. Does anyone know how to make you labels more visible when in the imagery layer?

I put a white halo around my text in the ArcMap document before I publish the service.

My background is white, so you don't see it normally, but when you switch the basemap to an image, now all the labels stand out with the white halo.

Just one way,
