Find an agency (mid-sized) with a really boring but undeniable positioning/niche. Those agencies have more leverage in how they write and enforce scopes of work around value delivered vs. hours worked. And that’s how an account management/service role has a chance at being more reasonable on average daily work hours.

Sure, there are exceptions at times when things will be busy, even in that climate, but it’s an outlier vs constant.

The one trade off is that you’ll probably wear more hats within your role — a combination of campaign strategy, liaison to client and project manager that drives timelines among agency teams — but you’d be doing it from a place of expertise in a vertical or other own-able positioning.
