As Michelle Bennett and coworkers write in their 2014 Commentary entitled “The ‘Welcome Letter’: A Useful Tool for Laboratories and Teams” published in the Journal of Translational Medicine & Epidemiology:
“Many PIs seem to assume that their expectations about how the lab functions make so much sense that they do not have to spell it out. Consequently, when confronted with lab members who do not meet their expectations, they often attribute the problem to the lab member’s personal failings. Unfortunately, this can result in loss of trust, miscommunication, and frustration on both sides.”
The Welcome Letter is a living agreement - should circumstances arise that change expectations, e.g. a global pandemic or the onslaught of AI tools, revise accordingly.
