In the interest in enjoying MY job again, here is a list of things that would be even worse:
Job at a sewage treatment plant.
Working as a janitor at Wal-Mart. Check that–just working at Wal-Mart.
Past veterinary jobs I’ve had: Emergency where I would work 12 hour shifts with literally no breaks, AND the doctors would be MIA, Aurora vet hospital with pretentious and entitled clients and cold co-workers, DVVH with a mid-life crises boss who scape-goated me, or even Noah’s Ark where I had to spend 3-6 hours per day walking/cleaning/treating a high volume of animals with irresponsible co-workers.
Any night job. 9 PM-4:30 AM will. Not. Work.
Working at the food stamp office, DMV, or any other disgruntled government operation.
Any type of engineer or mathematician.
Sales–especially if travel is required.
