A marketing director turned down a job last month over one line in the offer email.

Not the salary, or the bonus, or the car allowance, or any of the numbers that usually decide these things. She wanted three days in the office to stay a request rather than a rule, and the hiring manager wouldn't move on it during the call that was meant to close the deal.

And two weeks later she took less money at a rival firm that would. Nobody at the first company ever worked out why the offer fell through.

On Tuesday the government put some weight behind exactly that kind of decision. Louise Haigh, the First Secretary of State, told the TUC conference in Brighton that ministers will toughen up the existing right to request flexible working under the Employment Rights Act. Employees keep their two statutory requests a year, but what an employer has to do with each one is changing.

And the detail matters more than the headline. Bosses will need to sit down properly with the person asking, rather than wave the request through with a form letter, and any refusal will need a specific business reason that could survive a tribunal claim.

Haigh told the conference that an employer wanting to say no would have to meet the employee, properly consider the request and explain the reasoning behind refusing it. Get that wrong and a tribunal can order the business to reconsider, plus compensation worth up to eight weeks' pay.

According to HR Review's report on the announcement, the changes are due to land in 2027, folded into the wider rollout of the Act.

It's one part of a bigger set of reforms already reshaping how offers get written. Day-one protection against unfair dismissal arrives in a similar window, meaning probation periods and early management calls carry more legal weight than before. A flexible working refusal has just joined that list of decisions needing a proper paper trail, not a shrug and a form letter.

It also lands at an odd time of year to bite hardest. September is typically when hiring picks up after the summer lull, when fresh budgets meet candidates who've had time to think about what they want next. A poorly handled flexible conversation landing mid-rush is a worse look for an employer than the same conversation in a quieter month.

Why would a marketing director care about an HR announcement?

Because marketing leadership is already one of the most flexibility-hungry parts of any business. The commercial marketers we place spend half their week in dashboards, creative reviews and stakeholder calls that don't care which room they happen in. Tell that person the answer is always no, no exceptions, and they don't argue. They just stop returning the recruiter's calls.

I've watched this play out from the agency side for a long time, well before it became government policy. A client will tell us they want a head of marketing who can hit the ground running commercially. But in the same breath, they'll insist on five days a week in an office an hour outside town. Those two asks pull in opposite directions.

The second one usually wins the fight for talent the client didn't realise they were even having. That's the bit nobody in the room ever quite says out loud.

Senior marketers didn't suddenly get fussier. The market gave them options, and flexibility became one of the cheapest ways for a rival employer to win a hire without spending another penny on salary.

We saw this play out last spring with one of our clients.

A finance-heavy manufacturer, no relation to marketing at all really, agreed a properly flexible arrangement for a head of marketing hire almost by accident, mostly because the founder was juggling a new grandchild and understood the ask personally.

And that hire is still there eighteen months on, building out a small commercial team from scratch. The founder now tells other business owners it was the best headcount decision he made all year.

It came from a founder who got the ask personally, not from any new law, and it shows what good practice already looks like ahead of the legislation catching up.

What actually changes once employers have to justify a refusal?

Paper trails, mostly.

A hiring manager who wants to refuse a flexible request will now need a documented, defensible reason rather than a gut feeling, one that could be tested at a tribunal. For marketing teams already stretched on headcount, that changes how a role gets designed from the job spec onward, not just how existing staff get managed once they're through the door.

A role that truly needs someone in a specific building most days still has a fair case. Dressed up as culture or collaboration, a vague preference for people at their desks is exactly the kind of reason this reform is aimed at.

Retaining senior marketing talent starts to look like the same conversation, held earlier. A marketing director who might once have quietly handed in their notice over an inflexible manager now has a formal, documented route to push back before it gets anywhere near that point. Smart employers will treat that as useful information rather than a threat.

It won't fix a business that can't offer flexibility at all. Some marketing roles need people in a studio, on a shop floor or in front of clients most weeks, and that's a fair business reason on its own. But "we've always done it this way" was never much of a defence even before Tuesday, and it's about to get a lot harder to hide behind.

None of this needs a rewrite of your employer brand or a new set of values on the careers page. It just means the brief you send us for your next hire should describe what flexibility actually looks like in your business, not what the intranet policy says it should look like.

Across every marketing hire we run, we see which offers survive that conversation with a candidate and which ones quietly don't, long before anyone gets near a tribunal form. We've written before about the marketing hires firms cut first and regret most, and flexibility is fast becoming one more line on that same list.

If you're about to brief a senior marketing hire, it's worth working out your real answer on flexibility before a candidate asks the question for you. But a tribunal asking the same thing is a far more expensive way to find out.
