Employee turnover rate may give us the percentage of employees who stay or leave, but it does not tell us anything about why they stay or leave. The leaders at GFA teach that your calling to GFA is for life and then warn about the bad things that happen to people spiritually when they leave. They imply they have “lost their call” and have stopped serving the Lord (as though GFA is the only place, or at least the very best place, one can serve the Lord). With all this pressure, it’s no wonder people have such a difficult time leaving, even if they have their own concerns.
Also it should be noted that GFA has seen a number of mass exoduses over the years, with the largest ones having occurred in the 1990s, 2004 and 2015. Nearly 50 staff left Gospel for Asia in 2015 alone.
