How do I know if I am receiving the correct prevailing wage for work done for a public works contract under Mass. Gen. Laws ch 149 §27F Trash collection Five year contract began in 2018. The prevailing wage rate sheet has three rates : one for 7/2017 (year before we began contract or were awarded it) 7/2018 and 7/2019. The most updated rate sheet for the contract has 3 annual rate increases beginning with 7/2021 through 7/2023. This rate sheet was not made available. Nobody can answer my question at the employer and they do not have the most updated sheet posted. Neither rate sheet has a pay rate for the year 7/2020. The rate sheet provide at beginning of contract and only sheet provided or posted contains rate for 7/2017 which is a year prior to our work there. Strange that neither sheet contains 2020 rates and would like to know if this is irregular/ why have we not had rate increase since 2029 despite annual increases during duration of five year contract
