<html> <body> Jeff - If you suspect loose bridge pins, are there any that are visually suspect, such as hairline or larger bridge cracks, or gapping in the wood surrounding the bridge pin?  Have you taken careful downbearing measurements to determine the presence or absence of negative front bearing? Such a condition can induce distortions in string termination, causing both false beats and tuning instability?  Have you tried tapping (lightly) strings to bridge?  Also, tapping bridge pins themselves can sometimes clear up tonal problems. A bit more specific information, such as area of scale affected, or circumstances in which instability is observed, might aid in remote diagnoses. With regard to Chicken Little syndrome, you probably need to make some choices.   You may want to survey, on your own time, the condition of the pianos, facilities, and the demands, and present a proposal to the responsible person or persons.   Based upon the response you  receive, you need to determine what works for you.  If you continue to receive inadequate resources to do the kind of work you feel is needed, you probably need to either do it anyway, chalking it up to gained experience, or, if you can afford to, walk away from it.  Of course, I'm speaking in generalities, not knowing anything of your particular situation, but, as such, the biggest challenge in these circumstances is figuring the politically adroit way to direct the general communal distress towards those who have the power to affect a change.   Good luck.
