AI Will Handle 36% of Marketing Work by 2028 - And Companies Are Firing Non-Adopters Now

60% of companies globally are planning to lay off employees who refuse to use AI. That’s not a prediction - it’s from a 2,400-person executive survey by Writer (April 2026). The same week, at Gartner’s Marketing Symposium in London, analysts announced AI will automate 36% of marketing work by 2028, up from 16% today.

What Gartner Said at Marketing Symposium London

At their Marketing Symposium/Xpo in London (May 11-12, 2026), Gartner released two surveys with a conflicting story at their core.

Marketing leaders expect AI to automate 36% of marketing work by 2028 - more than double the current 16%. CMOs are already allocating 15.3% of marketing budgets to AI. But only 30% of CMOs say they are actually ready to scale AI capabilities within their organization.

The gap between expectation and preparation is the real story. Leaders can see the wave coming. Most aren’t ready to swim.

The 4.5x Productivity Gap - and What Companies Are Doing About It

Writer partnered with Workplace Intelligence to survey 1,200 C-suite executives and 1,200 employees across the US, UK, Ireland, Benelux, France, and Germany. Published April 7, 2026.

The productivity split is stark. AI power users - those who use AI seriously and systematically - save 9 hours per week. Non-users: 2 hours per week. That’s a 4.5x gap.

What companies are doing in response:

• 60% plan layoffs for employees who won’t adopt AI
• 77% warn that non-AI-proficient employees won’t advance to leadership roles
• 92% of C-suite are actively building an “AI elite” - a tier of high-AI-proficiency employees who receive preferential compensation and promotion paths

The paradox: 44% of Gen Z employees - supposedly the most digital-native generation - admit to actively sabotaging their company’s AI strategy. This includes using unapproved tools, feeding company data to public AI systems, or simply refusing to adopt. The result: 67% of companies have already experienced data breaches from unapproved AI tools.

The ROI Tension Nobody Wants to Talk About

Here’s the uncomfortable data sitting underneath all of this: only 29% of executives report meaningful ROI from generative AI. Only 23% see real returns from AI agents. Yet 59% of companies are investing over $1 million per year in AI anyway.

So you can be fired for refusing AI - while using AI doesn’t guarantee better business results.

54% of C-suite say AI adoption is “tearing their company apart.” 75% admit their company’s AI strategy is “more for show than actual internal guidance.” 38% of CEOs report high stress levels about their AI strategy direction.

This isn’t a technology problem. It’s an organizational change problem in an era without a playbook.

What This Means for Marketing Teams in Vietnam and Southeast Asia

The Gartner and Writer data reflects primarily large Western enterprises. But for Vietnam’s marketing market, there’s an additional layer of pressure.

Vietnam leads Southeast Asia in AI adoption, with 81% of users engaging with AI tools daily (regional research, 2026). ChatGPT alone holds 81% market share among AI tool users in the country.

But high adoption rates don’t automatically translate into the 9-hour-per-week savings that separate power users from laggards. Vietnam’s marketing market is dominated by agency structures, where cost efficiency determines competitive survival. When clients start benchmarking service pricing against what AI can produce faster, agencies without AI-fluent teams lose margin before they lose the account.

The real question for marketing teams isn’t “are we using AI?” anymore. It’s “are we operating at a level where we would survive the productivity benchmark - or are we in the 60% that gets cut first?”
