My bosses have found a solution to the not-enough-work problem: data entry! Yesterday my manager handed me a stack of mixing records that need to be put into a spreadsheet. Luckily, this is the kind of tedious, repetitive task that I love, so it's an excellent fit for me.
Unfortunately, they also announced that one of my coworkers has given notice, and I'll be taking over some of his duties, which include washing out our mixing buckets... my least favorite thing. But hey, it's work. My job description does include "fill in as needed," so I have to accept working outside my comfort zone a little.
