Ours doesn't "supply" them either. I have a plastic case I wear with my badge and I keep a set in there. Replace them when they get funky. Never really realized that they SHOULD give them to us! They SHOULD!!
I know I should wear them and I do. I also know that they are dirt cheep. It was more the principal of weather or not an airline should provide hearing protection to pilots. I know they provide ear protection to all the other ramp personel.
