Don't do it. You might be screwing your sim buddy over in the process. If you have a fellow new hire as a sim partner and you drop some MIL leave during training there is a good chance that he/she will be rolled to the next class to get a partner. They will get an extra few weeks off, but remember you are on training pay of about $4000/mo until you get done with OE. If you take MIL leave during training, you just might be taking money out of someone's wallet in the process.
