Can you elaborate on this?
There are plenty of locums gigs out there that people can do. Often times these gigs are in rural places that are understaffed and need people for either short stints or to cover empty slots. Most of the time they're in fields like Anesthesia and ER where there's no need for continuity of care or need for clinics. A warm body just comes in and does the work and leaves. Probably not realistic for surgical fields, IM, FM, psych ... maybe hospitalist medicine. There are some upsides and downsides and the perks can be vary from gig to gig.
Goods:
1. you get to travel and see different places
2. they cover housing, travel, tail malpractice coverage
3. they often pay pretty well too
4. flexible schedule for you as you can work for a bit and then decide you want to take a month off before hitting up your next gig.
5. good way to supplement your income if you do shift work and have time.
Bads:
1. there's a reason these places can't fill their spots. They either have a malignant administration, they pay poorly, location is horrible.
2. inconsistent income stream since you're always looking for another gig
3. hard on the family if you have a family
4. you're always traveling
5. stigma. The general sense is that people who do these gigs are often the bottom of the barrel. There's a reason that they cant find or stay employed with one group (i.e. lotta red flags) hence are forced to do these traveling gigs. So if you're a brand new grad and you do this for a bit then decide to apply to a more traditional group, they might wonder what's wrong with you that you can't find a stable gig right off the bat. Not always true but it was what I was told when I was considering doing this for a bit.
