We do a type of self scheduling. I choose Sun, Mon, & Tue for my base days....then every 3rd weekend I work Sat, Sun & Mon. I have been working this for months. I planned a trip to see my daughter around this schedule. I just got my newly posted one & it has me working on the days I am always off. You guessed it the days I have plane tickets & will be gone...plus another odd day thrown in later in the schedule. I chose this so I would know when I am working & could plan things. I am hoping this is just a mistake. I explained it on a copy of my schedule & turned it back in....geezh. What a mess! Guess I just wanted to vent to someone....my plane tickets are non-refundable! Any advice?
