Is this legal? (Serving tables)

Hello everyone,

I work as a server at a restaurant. I recently learned that, as part of our tip policy, the owner takes a portion of the tips earned by the servers and gives it to the kitchen staff to cover the recent minimum wage increase. When Seattle raised the minimum wage from $17.00 to $20.30 per hour, he started taking $3.30 per hour per employee from the servers’ tips and adding it to the back-of-house hourly wages. He also gives the kitchen 5% of food sales from our tips as well. Is this a normal tip pool? Or am I getting screwed?

Thanks. Let me know if you have questions.
