UK Living Wage = £8.25 an hour (voluntary rate which an employer outside London can sign up to)
Negotiated hourly rate of pay. This is a rate agreed between an employer and trade union following collective bargaining. A better deal all round for workers. One you get to vote on. Where a union is recognised an employer must legally provide union members with full details of company accounts, pay costs and staffing levels.
Tips can't be used to make up your legal minimum. Unite changed the law to make sure this can't happen any longer.
