What is an anesthesiologist's vacation days breaks and hours?

That, as with most other jobs, varies by each medical facility. Some are more generous with vacation time than others, but as for the hours worked, and the 'breaks', that really doesn't work the same as with a typical office job. An anesthesiologist is a medical Doctor Who has specialized in the field of anesthesia; he/she may sometimes have to work for many long hours with no break. During a lengthy surgical procedure, such as a heart transplant, trauma surgery, back surgery, etc., the anesthesiologist simply can't say, "Hold it, I need a cup of coffee", any more than the attending surgeon could. The anesthesiologist actually does much more than just make sure the patient is 'asleep' during the procedure; his/her responsibilities go much further than that, and there is a lot more involved than most people realize. There are also no set hours as there are in a nine to five job. He/she is often scheduled for a number of surgical procedures in a single day, as well as taking their 'on call' shift. And since there can be no way to predict how long many procedures will take, or how many unscheduled surgeries there may be (such as accident victims), then there is no way to give a set number of hours they will work.
