Your First 90 Days

The first three months of any job are an extended audition. Not for whether you'll keep the job, but for what kind of employee people will think of you as, often for years. First impressions at work are sticky. They're hard to reverse and easy to establish correctly from the start.

A few things that matter most early on:

On proving yourself

The impulse to make a big impression fast usually backfires. The people who tend to do well early in a job are the ones who do their work well, are easy to communicate with, and don't cause problems. That's it. That's the whole formula for the first few months.

Communicating With Your Manager

Your relationship with your direct manager has more impact on your day-to-day experience than almost anything else at work. A good relationship doesn't require that you like each other. It requires clear communication and shared expectations.

Understanding what they actually want

Different managers want different things, and a lot of workplace frustration comes from assuming you know which kind you have. Early on, pay attention to:

If you're not sure, just ask. "I want to make sure I'm communicating the way that works best for you. Do you prefer quick check-ins, or would you rather I come to you when something needs a decision?" Most managers will be glad you asked.

Giving your manager no surprises

The thing managers dislike most is finding out about a problem late, especially one they could have helped with earlier. If you're stuck, falling behind, or something has gone wrong, telling your manager early almost always goes better than waiting until they notice themselves.

When you do raise a problem, come with what you know and, ideally, what you've already tried. "The client hasn't responded and the deadline is Friday. I've followed up twice. How do you want to handle this?" is far better than "There's a problem with the client." You've done the thinking. You're bringing them a decision, not a mess.

Asking for feedback

Don't wait for a formal performance review to find out how you're doing. After you've been in a role for a month or two, ask directly: "Is there anything I could be doing differently or better?" Most managers don't volunteer this unless something is seriously wrong. Asking for it signals maturity and makes you easier to manage.

Professional Communication

A large part of how you're perceived at work comes down to how you communicate: in email, in meetings, and in conversation. None of it is complicated, but it's not obvious if nobody's ever shown you how it works.

Email

Meetings

Slack, Teams, and messaging tools

Instant messaging tools at work aren't the same as texting with friends. A few things worth knowing:

Professionalism: What It Actually Means

"Be professional" is advice that often gets stated without being explained. In practice it comes down to a few things:

Reliability
Do what you say you'll do, when you said you'd do it. If something changes, communicate before the deadline, not after. Nothing builds trust faster than being the person people know they can count on.
Discretion
Keep internal information internal. Don't share colleagues' salaries, gossip about coworkers, or talk about your company in ways that could embarrass it. Even venting to a friend about your job carries risk. What you say outside work can get back to you.
Ownership
When you make a mistake, own it directly. "I got the numbers wrong in the report and I've corrected it" goes far better than deflecting or explaining at length. One direct acknowledgment and a fix is almost always better received than a long justification.
Separating emotions from work
Frustration, disagreement, and disappointment are all normal at work. How you handle them in the moment matters. Reacting emotionally in a meeting or sending a sharp email when you're annoyed creates problems that are hard to undo. When something bothers you, give yourself time before responding.
Reading the room
Some offices are formal; some are relaxed. Some managers want lots of communication; others want autonomy. Some teams joke around constantly; others are heads-down. Watch how the people around you operate before assuming your default is the right fit.
Appropriate dress
When in doubt, dress one level more formal than the environment requires, until you have enough context to calibrate. It's easier to dress down later than to undo a first impression you didn't mean to make.

Managing Up

Managing up means actively helping your manager do their job better, which in turn makes your own work life easier. It sounds like something only ambitious people do, but it's actually just good communication with a direction attached to it.

Workplace Conflicts

At some point you'll disagree with a colleague, feel like you were treated unfairly, or have a genuinely difficult working relationship with someone. How you handle it matters more than the conflict itself.

On office politics

Office politics exist in every workplace, whether anyone admits it or not. The best way to handle them is to be someone people trust: do good work, be easy to communicate with, don't talk badly about colleagues, and stay out of drama you don't need to be in. That's not naivety. That's a durable strategy.

Remote and Hybrid Work

If you're working remotely, fully or partially, the basics of professionalism still apply, but a few things shift:
