When your best people spend their days formatting slides

Senior hours, junior work, paid out of margin and morale

If you ask a marketing director where their week goes, they’ll list things that sound like director work, strategy, planning, stakeholder alignment. If you sit next to one for a day, you’ll see something else. They’re rebuilding a slide because the deck got broken in PowerPoint. They’re rewriting a junior writer’s draft because it’s two clicks away from being the deliverable. They’re chasing a revision through three Slack threads because the comment system in Google Docs is a graveyard.

This is the senior-on-junior-work tax. It’s the most expensive cost line on most marketing teams, and it’s invisible because everybody is busy and everything is “almost” the right level of work. It deserves a name, because once you can see it, you can fix it.

What the tax actually looks like

Three patterns, all of them universal.

The 80% draft becomes a 100% rewrite. A junior produces a draft that’s directionally right. A senior reviews it. Instead of editing in place, the senior rewrites two thirds of it because that’s faster than explaining what’s wrong. The junior didn’t get better, the senior burned 90 minutes, and the deliverable is identical to one the senior would have produced from scratch.

Tooling work eats senior hours. PowerPoint files break. Figma exports the wrong size. The CMS strips formatting. Every team has someone senior who happens to be good at the tool, and they become the de facto last-mile production person whether their job description says so or not.

Coordination overhead lands on the wrong people. “Where are we on the campaign?” gets routed to the strategist instead of the project manager because the strategist actually knows. They spend two hours a day in Slack triaging things that should have been handled by structure, not by them.

The combined effect is roughly 30–40% of senior time spent on work that is, by any reasonable definition, junior work. That’s a real number, and it’s why the team’s “strategy time” never materializes regardless of how many calendar blocks you add.

Why “just hire more juniors” doesn’t fix it

The intuitive fix is more capacity at the lower end of the org chart. It doesn’t work, for reasons that surprise most leaders the first time they try:

• More juniors means more drafts to review. Senior review hours are the bottleneck, and adding juniors just compounds the problem upstream.
• Coordination overhead goes up faster than capacity. A team of 8 has more than twice the meeting load of a team of 4.
• The senior-on-junior-work pattern is structural, not capacity-driven. The reason the senior is rewriting drafts isn’t that there aren’t enough juniors, it’s that the juniors don’t have the brand context to start a draft closer to the line.

Adding people to a team with this problem makes the team worse, not better. The fix has to be structural.

Three changes that recover the hours

1. Move the brand context out of senior people’s heads

The single biggest reason senior people end up rewriting drafts is that they’re carrying the brand context (voice, audience, prior framings, banned phrases) implicitly. The junior didn’t know that you don’t say seamless on this brand because three customers complained about it. They didn’t know that the last three posts on this topic landed on a specific framing. They couldn’t have known, because the knowledge wasn’t anywhere they could see.

When this context gets externalized into a structured brand memory (not a 40-page brand book nobody reads), drafts start much closer to the line. The senior edit becomes “tighten and ship” instead of “rewrite from scratch.” This is the biggest single lever and it’s the hardest one to actually pull, because it requires admitting that the brand isn’t really in the brand book.

2. Decide what work is allowed to be imperfect

A lot of senior rework is driven by an unstated standard: every piece must hit the same bar regardless of what it is. That’s expensive. A LinkedIn post that ten people will see internally doesn’t need the same review depth as a campaign email going to 30,000 people. Make the tier explicit:

• Tier 1 (high-stakes, customer-facing, durable): full senior review.
• Tier 2 (recurring, channel posts, internal comms): senior reviews on sample, not every piece.
• Tier 3 (utility, formatting, repurposing): no senior review, structural template only.

Most teams have an implicit Tier 1 standard applied to everything. Roughly half of the team’s output is Tier 2 or 3, and applying senior review to it is pure waste.

3. Get the formatting and tooling work off senior people on purpose

If your most expensive person is the one who knows PowerPoint best, fix that. Either invest in the tooling (templates, design systems, CMS layouts that don’t break) so the production work doesn’t require senior hands, or designate someone whose actual job is the last-mile production. Both work; “the senior person quietly absorbs it” doesn’t.

This sounds like the smallest fix on the list. It usually recovers more hours than the other two combined.

What this looks like at quarter-end

A team that pulls these three changes typically gets back 25–35% of senior time inside one quarter. That time doesn’t appear as “now we ship more pieces.” It appears as the strategy work that the team has been complaining they can’t get to. The output volume stays roughly the same; the leverage of the team goes up significantly.

The senior-on-junior-work tax is the part of marketing operations nobody warns you about. Once you can see it on the team’s calendar, the fixes are obvious. The hard part is admitting how much of it is happening.
