I am a furniture installer, and we are never told when we work on a PW job, but every so often my employer will go in my payroll history and “adjust” payment for a job that I worked on or completed up to several months prior. Sometimes I will see an hour or more on my current paystub marked as PW, when I spent anywhere from one hour to a full week even on a specific job. Is this legal? And why am I not being told when I am working a Prevailing Wage job???
