No it's not my birthday, not yet.
The National Minimum Wage is 10years old. Being some 30 years older I remember the fuss when it was introduced. The unfortunate thing is that it was, indeed still is, necessary. Unscrupulous employers were not paying a fair wage for a fair job. The downside is that some employees end up being paid a fair wage for a poor job! However there are ways to resolve such problems.
Current minimum wage rates are £5.73 an hour for those aged 22 and over, £4.77 for those aged 18 to 21, and £3.53 for 16 and 17-year-olds. These are subject to change each October.
