I'll start by saying that in general, if you actually look at the trend toward branch hours, it has been to lengthen them rather than to contract them to try to reflect when people are actually able and want to do banking.
Are adjustments made on a case by case basis? Sure, it can happen, but in general it's ultimately all driven by viability. Is this branch viable? Is there a way I can repurpose it or reframe it to make it viable? If there isn't, what's my alternative and what can I do to try to maintain some degree of service to people in the community while recognizing that the branch, as it exists, simply isn't economically sustainable anymore?
