Latin America sits mostly between GMT-2 and GMT-5. That’s pretty close to US Eastern Time, right?
So managers think: “Great, no scheduling issues like we’d have with Asia or Europe.”
Wrong.
Brazil alone has four time zones. Chile and Argentina don’t follow US daylight savings schedules.
Colombia is an hour behind Miami half the year, then synced up the other half.
These small differences add up fast.
Three Schedule Models That Actually Work
Pick one of these before you even post the job.
Same-timezone model: Your Latin American team member works your exact schedule. 9am to 5pm Eastern Time. Or 9am to 5pm UK time if you’re in London.
This is simple. Great for roles that need constant collaboration.
Core-hours model: Define a daily overlap window where everyone must be online. Usually 3-5 hours. The rest of their workday is flexible as long as work gets done.
Example: “Be available 12pm to 4pm EST for meetings and quick Slack responses. Your other three or four hours can happen whenever works for you.”
This gives you real-time collaboration when you need it. Gives them flexibility to manage their day around family, appointments, or their most productive hours.
Most successful remote companies use some version of this.
Coverage model: Use Latin American staff to extend your operational hours beyond what your US or European team wants to work.
Think customer support that needs to cover evenings or weekends. Or development work that can happen while your main team sleeps, creating a natural handoff.
This only works if you’re upfront about it and compensate fairly. Don’t surprise someone with “oh by the way, we need weekend coverage” after they’ve already accepted the role.
Put It In Writing Before You Hire
Here’s what needs to go in your job posting and employment agreement:
Reference time zone: Always state hours in one clear time zone. “9am-5pm Eastern Time” or “10am-6pm GMT.” Not “morning” or “business hours.”
Include how you’ll handle daylight savings if it affects the role.
Minimum overlap requirement: “You must overlap at least four hours with our core team hours of 9am-5pm Eastern, Monday through Friday.”
Meeting expectations: Be honest about meeting frequency. “We have one weekly team call on Thursdays at 2pm Eastern. Department heads may schedule additional calls during your agreed working hours, but we aim to keep meetings under five hours per week total.”
Response time standards: “We expect Slack responses within 2-4 hours during your working hours. Email within one business day. No expectation to respond outside your scheduled availability.”
Right to disconnect: “Messages sent outside your working hours do not require immediate response. You’re encouraged to set Slack to Do Not Disturb outside your availability.”
You’re telling someone exactly what you need so they can decide if it fits their life. That’s how adults work together.
Co-Create the Final Schedule in Week One
Don’t just hand someone a schedule. Build it together.
First week, have this conversation: “Here’s what we need from this role. Here’s your preferred working window. How do we make both work?”
Use World Time Buddy or Google Calendar’s world clock view. Map their ideal local hours to your team’s time zone. Find the overlap that works for everyone.
Then write it down.
Create a shared document that says: “Maria works 10am-6pm Colombia time (11am-7pm EST October-March, 10am-6pm EST April-September).
Core availability for meetings and Slack: 11am-3pm EST. Flexible hours: 3pm-7pm EST for project work and async tasks.”
Put it in a calendar. Make it official.
Use Tools That Support Your Schedule
Stop doing time zone math in your head.
Google Calendar and Outlook both show time zones for every event. Enable that. When you send a meeting invite, your team member in Mexico City sees it auto-converted to their local time.
Default to async communication for everything except real-time decisions.
Use Slack or Teams for quick questions, but make it okay to respond hours later. Use Loom to record video updates instead of scheduling calls.
Use Asana or Trello or Monday to manage tasks with clear deadlines instead of urgent 10pm pings.
Save your synchronous time for things that actually need it. One or two predictable weekly meetings that everyone can plan around.
Quick standups during overlap hours. Strategy discussions that benefit from real-time back-and-forth.
Everything else? Async.
For Remote Workers: How to Set Your Own Boundaries
If you’re a remote worker in Latin America reading this, here’s what you need to do.
Before accepting any role, ask these questions:
“What hours do you expect me to be available in your time zone?”
“Do you have core hours where the whole team needs to overlap?”
“How many meetings should I expect per week, and when do they typically happen?”
“If a meeting needs to happen outside my local 8am-6pm, can I decline or suggest an alternative time?”
These aren’t pushy questions. They’re professional ones.
Any company that gets defensive about scheduling questions is showing you who they are. Pay attention.
Propose your own schedule clearly:
Don’t wait for them to figure it out. Say: “I’m available 9am to 5pm Argentina time, which maps to 8am-4pm EST during your fall and winter. That gives us four hours of overlap for meetings and collaboration.”
Show them you’ve thought about it. Make it easy for them to say yes.
Set up your tools to protect your boundaries:
Block off your non-working hours in Google Calendar. Set them to auto-decline meetings outside your agreed window with a note: “I’m not available at this time. Please schedule during my working hours: 9am-5pm Chile time / 8am-4pm EST.”
Use Slack’s scheduled Do Not Disturb. Set it to pause notifications outside your working hours automatically.
Update your status: “Offline – back at 9am Santiago time (8am EST).”
These small actions train your team to respect your schedule without you having to fight about it constantly.
Renegotiate when things drift:
Schedules creep. A meeting moves 30 minutes earlier because someone forgot about time zones. Then another. Soon you’re starting work an hour before you agreed to.
Gather examples. Send a friendly message: “Hey, I’ve noticed several meetings lately have been scheduled at 7am my time, outside our agreed 9am start. Can we reset to our core hours, or find times that work for everyone?”
If you’re consistently working extended hours or covering unusual shifts, ask for it to be formalized. Adjusted compensation. Comp time. A revised schedule that reflects reality.
You’re not being difficult. You’re being professional.
What This Really Comes Down To
Most scheduling problems aren’t actually about time zones.
They’re about unclear expectations and unspoken assumptions.
You can hire someone in Colombia or Argentina or Brazil and have perfect collaboration. Or you can hire someone two blocks away and have constant scheduling conflicts.
The difference is whether you had the scheduling conversation upfront.
Be explicit. Be respectful. Be willing to negotiate.
That’s what makes remote work actually work.
