Are Hydrophobic Clothes Bleach Proof?

Lately, there's been an issue at my workplace of people getting bleach stains (we use bleach to sanitize countertops) all over their uniforms. Mine was damaged so much that I had to get a new uniform... Which does come out of my pay. Seeing as the uniforms are a bright blue, we can't just redye them and expect it to turn out well. So I was wondering if purchasing some hydrophobic spray and spraying it all over the uniform will prevent it from happening again. Also what happens should I decide to wash the uniform while it's hydrophobic? Will it even get dirty in the first place and need washing?
