Hiya Knockout,
If we're talking about the Fed, it'll be one ID card for the person who's signed up with them. Normally the boss, unless you can get the employees paying your bills
Welcome to Cleanitup, while I'm on, and I have to tell you I'm deeply hurt you came to the window cleaning section second - but I'll let you off if you promise to fill in your signature and profile.
Let us know a few details about you, sole trader or captain of industry, out in the sticks or middle of a big city, just starting out or been on the tools for a few decades . . . you get the picture.
Oh, and if you're not already, when you're going to join the National Federation of Master Window Cleaners. Remember, that's a when, not if
All the best,
Davie
