I work as a research assistant in a lab. Part of my job involves following up with our research subjects, and scheduling their appointments. I have been working at this position since late November of 2016. This is the first job in my field that I have held.
After being hired, I and a colleague hired at the same time were trained by the person who previously held this position for about 1.5 weeks before they left for a new job in another city. There are currently no employees on our team that worked in this position prior to my employment.
Over the last several months, my supervisor has mentioned to my team that productivity has been low (The # of research subjects scheduled/# of subjects who completed a follow-up). We've attempted to bring productivity up, however the month-to-month average remains fairly steady.
Being concerned that I am not meeting my employers expectations, I have looked into past productivity records to determine more accurately the goals my team should be meeting, and if a low productivity at this time of year is to be expected/has been a trend in the past.
According to productivity reports from 2014-2017 my team was above average in productivity for the 2017-2018 year. The most recent year that outperformed us was 2014-2015, but the team responsible for that was double the size it currently is.
How should I respond when my supervisor brings up productivity being low, knowing what I now know? I am hesitant to mention that I've looked at past productivity reports, and our productivity is not low relative to the last several years. I'm worried my supervisor will take this the wrong way somehow.
Should I pro-actively bring this up? I was hoping to ask our PI (Princial Investigator, actual boss, not my supervisor) for a potential raise soon, however hashing out this 'low-productivity' issue may be better to do beforehand?
