Two proposals to raise the minimum wage in Lexington are now before city council. Council member Susan Lamb on Thursday detailed an alternative proposal to that offered by colleague Jennifer Mossotti. Lamb’s plan boosts the minimum wage to $9.00 an hour over three years, compared Mossotti's proposal of $10.10. Mossotti says another difference is her draft includes a provision for tipped employees. “We have to get over that first hurdle, we’re going to move forward with the basic increases in minimum wage, then we’ll go to the next step,” said Mossotti.
