Not presently, though I've worked alongside a couple people who work for them and it seems like it's not a bad gig.
As an agent, you need to "hang your license" with a broker unless you want to become a broker which requires a staffed office, at least 4 agents under you, more continuing education, and overhead from a physical office, etc.
Agents are Independent contractors, so in that regard it's not like you are working directly for broker, you just file your paperwork through them and they get part of every commission. Personally, it's been over a year since I even walked into my office, everything is now done electronically. Dropping off escrow checks, original signed contracts and picking up commission checks are really the only reason to go in and I usually send one of the agents I mentor to do that for me. The commissions are really good, but the work is full commission, so you don't get paid until you make a sale, so most agents have other incomes. Keller Williams is one of the most laid back firms and this is attracting agents from many other agencies. Other places will make their agents attend monthly or weekly meetings, some require so many hours of desk duty every year answering phones, and many are inflexible with their commission cuts. For example, sometimes agents will get down to a close deal and offer to give up some of their commission to make deal go through and some agencies won't let them or require them to pay brokers full cut before reduction, I recruited an agent two months ago I co-listed a property with for that very reason. Big loss for that agency as she's selling 3-5 mil a year. Also, KW will give agents part of the commission from agents they refer, so that's another attractive part.
