Make sure to check your work! Zoom out, and check different screen sizes.
Being on rotation does not mean you have to jump the minute a task comes in. Just monitor the tasks and be aware.
Tasks that can be completed reasonably within 1 hour or so MAX should be done that day, unless there are other things that keep you from getting to it.
All tasks should at least be acknowledged by the end of the day. Even if you do not get to it, give a comment to the next person in the rotation as a courtesy to explain the situation.
Anything that would run longer than 2 hours should be considered a project and sent to Niq or Dave for assignment to an appropriate designer.
If you are not on rotation and need something to do, you are free to grab tasks as needed, just make sure you take ownership of the task to avoid any lines getting crossed.
