third shift uniform

Hi i am working the third shift for this season and i wanted to know does anyone know what kind of uniform they wear for the people that work during closed hours?

I recall seeing the trash pick-up people a few times while walking through the park to Golds...and if I remember correctly,they wore uniforms like the male sweeps do (yellow button up shirt,khaki shorts).

And the maintence guys wear the same uniform that the ones in the daytime wear.
