On 5 October, Barclays‘ new office-attendance rules took effect: three days a week for most UK staff, four for senior people. Thousands of employees had backed a union campaign against the change, and some won the right to defer until 2027. The same week, a UK construction firm gave its 125 staff contracts that let them compress full-time hours into four days. Disney, meanwhile, has extended a four-day office mandate to people who were hired as remote.

On LinkedIn, the return-to-office debate is mostly argued as ideology: culture against autonomy, collaboration against focus. Read the employee complaints closely, though, and a more practical picture emerges. Commute costs. Childcare. School runs. Finding a quiet hour to do actual work. Most of these are scheduling constraints, and in most companies those constraints are invisible to whoever books the next meeting.

The calendar nobody can see

Every hybrid or compressed schedule creates commitments that sit outside the work calendar:

• the 7:40 train that makes a 9:00 meeting impossible on office days;
• the 3:15 school pick-up on the days you work from home;
• the Friday you’ve swapped for a longer Monday under a four-day contract;
• the client whose calendar lives in their Microsoft 365 tenant, not yours.

Most people keep these in a personal calendar, or a second work account, or their head. Their colleagues book against the one calendar they can see. It shows a clean afternoon, the invite goes out, and the person on the receiving end has to decline, explain, and negotiate. Do that three times a week and “flexible working” starts to feel like constant justification.

When a policy lands badly, part of the reason is often that the calendar never reflected it. The schedule exists on paper and in people’s lives, but not in the calendar that meetings are booked against.

Make the constraint visible, not the detail

The fix isn’t to put your dentist appointment on your employer’s calendar. It’s to make sure your employer’s calendar knows you’re busy, without knowing why.

That’s the problem I built Calendrz to solve, using what we call availability mirroring. Connect your work, personal and client accounts to Calendrz. Whenever you’re busy in one, every other calendar is auto-blocked with a private marker: no title, no attendees, no location, only “this time is taken”. Cancel the original and the blockers disappear.

For a hybrid schedule, that changes the daily friction:

• Office-day commutes go in your personal calendar once as a recurring event. Your work calendar shows you busy from 8:00 to 9:00 on Tuesdays and Thursdays, and nobody needs to know it’s the train.
• Caring commitments are protected automatically. The pick-up window is blocked everywhere, every week, without a conversation.
• Compressed weeks are easier to live with. Block the day off once and every calendar you’re connected to respects it.
• Client calendars see your availability without seeing your other clients, which matters when you’re bound by an NDA.

A five-minute setup for a hybrid week

1. Connect every calendar you’re accountable to. Work, personal, side projects and client tenants. Google and Microsoft 365 are both supported.
2. Put the fixed constraints in your personal calendar. Commutes, school runs, gym, appointments. Recurring events are best.
3. Add focus blocks where you work best. If deep work happens on home days, protect those mornings once and let mirroring carry them across.
4. Label your markers if you want context. Summary macros let a blocker read “Busy (personal)” or show which account it came from, and marker colours make the week easy to scan.
5. Share a single availability link with people outside your organisation, so they choose from times you’re actually free across every calendar, not only your work one.

What leaders can take from this

If you’re setting an office policy, the calendar is where it will succeed or fail day to day. Three suggestions:

• Anchor meetings to office days. If people are asked to come in for collaboration, collaboration should happen when they’re there. Don’t schedule the all-hands on a remote day and then ask why the office is empty.
• Treat a blocked slot as a boundary, not an obstacle. A “busy” marker with no detail is someone managing their life responsibly. Don’t make them explain it.
• Measure meeting load alongside attendance. A three-day mandate that turns office days into back-to-back video calls from a hot desk has missed the point.

Policy is the debate. The calendar is where it plays out.

The return-to-office argument will run on LinkedIn for a while yet. Whatever your company decides, the practical work is the same: make sure every calendar that people book against tells the truth about when you’re available.

(Disclosure: Calendrz is my company, and this is exactly the problem it exists to fix. If your hybrid week keeps getting booked over, give it a try.)
