Their missionaries are fantastic, but their stateside personnel staff have no problems abusing and discarding their missionaries if they feel it will benefit the appearance of their mission

-to clarify a little further, I grew up as a MK with SIM for +10 years. I am intimately familiar with a great missionary who had been with SIM for 25 years and who was falsely accused by someone. This missionary had up until then never been accused of misconduct like this in decades of working overseas. SIM in written form and in conversation lied to this missionary, fired them before the authorities ever finished their investigation (and without ever getting the story from the side of their missionary), and provided literally tens of thousands of dollars to their false accuser to sue them in court. Ultimately the authorities and legal experts investigated the missionary and cleared them of these false allegations. Despite this SIM has refused to apologize, make restitution, and continues to persecute this missionary. The personnel department and leadership at SIM will have to answer to God for what they have done. Thankfully justice is in His hands despite SIM's actions.

In summary, if you work for this organization, perhaps you will have a good outcome. From my own experience I can definitively say though, that if something ever happens to you outside of your control and despite your innocence, if it in any way could look bad for SIM they will aggressively jettison you. In this case, not only did they fire this missionary but went beyond severing ties and actively persecuted them. In my professional career I have worked in several large organizations, yet have never seen anything like the shocking treatment of an employee as has been perpetrated by SIM.
