We are a combination department with IAFF Representation for the career staff. We work the following schedule: on-off-on-off-on-off-off-off-off then start over with the same schedule. What I'm looking for is the FLSA ruling on trade days. I have heard that it is a contract between the two people trading and you pay them as though there was no trade. (IE firefighter A works for firefighter B on Tuesday, firefighter B gets paid for it). Can someone direct me to the opinion letter or whatever you use for your contract language? Thanks for any help on this.
