I have a call coming up now, I may sign up to do a second job, because I got nothing better to do. And since I switched from night shift to day shift my mental state is in decline. I.e. I used to work 7*17 nights and 34 weeks off. Now I work much more during the day but have much less time to travel. Going somewhere next week all alone..
I work 9-6 mo-fr 38weeks, so 184 total shifts. I plan to add a side job doing occasional weekends at 600/hr and also thinking of 7pm-12am side job. If I keep this up several years I could just retire.
