It is the job that you signed up for. There is no surprise as to what is expected of you when you go to work. Typically, a day at work for an Air Traffic Controller consists of arriving to work in uniform to receive a conditions brief regarding weather, runway, airfield, airspace,etc. A controller will work in position (actively talking to pilots/giving direction) for 2 hours with 30 minutes of break time in between positions. There are multiple position certifications required to work in a Radar Approach Control facility and multiple years of training to accomplish.
