Suppose you're hired January 4, 2019. You don't get profit sharing for the entire 2019. Lame, I know...

You're off probation in January 2020 and conversely, 2020 is the first year you were employed from January 1 until the end of the year making you eligible for profit sharing. Now, if profit sharing is paid in March, you don't see your 2020 profit sharing until March 2021.

26 months on the property, and a 3rd year FO.

Moral of the story... get into December class if at all possible.
