Oh RLY? So you're entirely booked. For the next 6 months? You have your daily life scheduled out and everything?
and if all the "customers" are internal you are doubly fucked.
i play the role of the internal customer for some of our internal software. you make a ticket to fix something that has been a problem, you make 6, you get ahold of the project director and they tell you its not a problem to be fixed, but a feature to add to the backlog that is about 3 years long. and you give up, and you keep doing the work around that you figured out and bide your time till some update makes it not work at all.
and then they think they can save money by moving half your job to India and they make you teach them all the work arounds, and it takes you longer to fill out the webform in sales force than to do the thing yourself. but now you have to answer 6 stupid questions from some dude in India every time you want that task that took you 10 min. completed. and you have internal meetings about why your expectations are not ment with the team in india, and you tell them, and they cancel all the future meetings so they dont have to hear about it.
also, FML.
