That was the old Northstar tactic. TONS of locums for the first two years (at the Hospital’s expense), to keep other folks around (make the job cushy to attract permanents). At the end of the two years, it’s time for the “come to Jesus” meetin’, where they tell all the permanents how much harder they’re gonna be working (cause the hospital money for locums is gone).
As mentioned, the first couple years are usually the “best” of these gigs (assuming they can find plenty of locums, which is NOT a given in today’s market, even at high pay). Don’t go buying that massive house until that first contract has passed. The end of that “honeymoon” period can be a real beeyotch, sometimes....
