The first 90 days of a new assistant how to earn trust in 30, 60 and 90 days, for the assistant and for the boss

Days 1 to 30: learn the system before changing it

The first month is for understanding how the principal actually works, not how the job description said they work. Resist the urge to improve things in week one.

• Learn the people: who the principal's ten key contacts are, who may interrupt them, who must never be kept waiting, who speaks for the family
• Learn the preferences: meeting length, email style, how they want to be updated (voice, text, one summary a day), what they hate
• Learn the systems: calendar, inbox rules, shared files, task tool, WhatsApp groups, payment approvals, travel accounts; get access on day one or ask for it in writing
• Shadow before owning: for the first two weeks draft replies and proposed calendar moves for approval, then take over gradually
• Write everything down in a working handbook: contacts, preferences, passwords location (not the passwords), recurring dates, vendors; this becomes the handover file later
• Goal by day 30: no double bookings, no missed message of the kind the principal considers urgent, the principal has stopped checking the calendar themselves

What to ask the boss in the first week

Most principals do not brief; they expect the assistant to ask. Ten questions in the first week prevent most of the surprises of the first quarter.

• What are the three things that, if they go wrong this month, would hurt you most?
• Who can book time in your calendar without asking, and who must go through me?
• What may I decide alone, what do I propose for your approval, what do you never want delegated?
• How do you want updates: how often, in which channel, how long?
• Which information is strictly private, and who in the company or family may know your schedule?
• Is there a payment rule: what I may pay, up to what amount, with what record?
• Which recurring dates and renewals exist, and where is the list?
• What did the previous assistant do well, and what went wrong?
• What does a good week look like for you?
• When would you like to review how it is going: day 30, 60 and 90?

Days 31 to 60: take ownership

The second month is where trust turns into delegation. The assistant now owns the routine and the principal only sees exceptions.

• Own the calendar fully: you move, confirm and protect time; the principal sees a daily brief, not the mechanics
• Own the inbox triage: you handle the second group yourself and bring the first group with a proposed answer
• Own travel end to end with the itinerary template and a backup option every time
• Start the renewals and payments list and run it 60 days ahead, with a short weekly summary of what is pending
• Fix two or three small processes you noticed in month one, after asking, not before: a template, a filter, a shared list
• Goal by day 60: the principal forwards messages with one word ("handle") and trusts the result; a weekly 20-minute review is in the calendar

Days 61 to 90: become proactive

The third month is where the assistant starts to see around corners. The job moves from reacting to preparing.

• Prepare meetings before being asked: agenda, background, the last correspondence, a decision needed
• Propose: a better rhythm for the week, a vendor to replace, a recurring task to automate, a trip to combine
• Build the relationships the principal relies on: their team, the family's household staff, the bank's manager, the PRO, the key vendors
• Hold the day-90 review yourself: what you now own, what still needs the principal, what you want to take next, and what you need from them
• Agree the next quarter's scope and, if the role grew, raise the package discussion honestly with a market estimate in hand; see our assistant salary guide
• Goal by day 90: the principal would be noticeably worse off without you for a week, and you both know it

A weekly rhythm that works

Routine is what makes an assistant reliable. A simple rhythm, agreed with the principal, carries the role.

• Daily, first 20 minutes: inbox triage in three groups, calendar check for the next 48 hours, one-line morning brief to the principal
• Daily, last 15 minutes: follow-up list updated, tomorrow's itinerary confirmed, open questions sent in one message, not five
• Weekly, 20 minutes with the principal: next week's calendar, decisions needed, renewals and payments pending, one improvement proposed
• Weekly, alone: the handbook updated, files filed, the vendors and contacts list current
• Monthly: the renewals list for the next 90 days reviewed, a one-page summary of payments and open items, a look at what could be automated
• Quarterly: a short review of scope, what grew, what should be delegated further, what training or tools you need

Mistakes that end probation early, and the employer's part

Most early exits are not about skills. They are about trust, communication and an absent brief. Both sides can prevent them.

• Assistant: changing systems in week one, before understanding why they are the way they are
• Assistant: hiding a mistake; a missed booking reported immediately with a fix is survivable, the same mistake discovered by the principal is not
• Assistant: over-asking or under-asking; agree in week one what you decide alone and bring the rest in batches
• Assistant: sharing the principal's matters casually, even with colleagues, even in general terms
• Employer: no brief, no access on day one, no 30-60-90 goals in writing; the assistant then guesses, and guesses wrong
• Employer: skipping the weekly 20 minutes; it is the cheapest way to catch a problem before it costs money
• Employer: write the probation period and notice terms into the contract and follow current UAE labour rules; our probation and notice guide explains the basics, and our guide to why staff leave shows the patterns to avoid

How we help

TLNT is a hiring consultancy. For employers we help define the role, search for candidates and assess them on real tasks before you meet the shortlist, and we give you a 30-60-90 onboarding checklist for the person you hire; you make the hiring decision and agree the terms with the candidate yourself, the person is employed directly by your company, the employer sponsors the visa and if it does not work out we find a replacement free of charge within the period set in the contract.

For candidates: send your CV through our candidates page or build one in the free CV builder; we let you know when an employer has a matching vacancy. Candidates never pay us.

Our fee is fixed for each role and agreed before the search starts. A 10% prepayment of the fee starts the search, the rest is due once the person has started work. If it does not work out, we find a replacement free of charge; the period is set in the contract. Consulting and CRM projects are priced after a free review.
