Your first 90 days at a new job set the tone for everything that follows. This guide covers workplace etiquette, professional communication, how to build relationships, and how to position yourself for growth.
The First Week: Listen More Than You Talk
Your first week is not the time to prove yourself. It's the time to learn how things work. Every workplace has unwritten rules — how decisions get made, who the informal leaders are, what the communication norms are, what "done" actually means. You can't learn these by reading the employee handbook. You learn them by watching, asking good questions, and listening carefully to the answers.
Professional Communication Basics
How you communicate at work shapes how people perceive your competence and reliability. A few fundamentals:
- Respond promptly. Acknowledge emails and messages within one business day, even if just to say you'll follow up later.
- Be clear and concise. State the purpose of your email in the first sentence. Use bullet points for multiple items.
- Match the formality of the environment. Watch how your colleagues communicate and mirror it until you understand the culture.
- Confirm understanding. When given instructions, repeat back what you heard: "So you'd like me to [X] by [date] — is that right?"
- Don't overpromise. It's better to under-promise and over-deliver than the reverse.
Workplace Etiquette That Matters
- Be on time — consistently. Punctuality signals reliability.
- Keep your phone away during meetings unless you're using it for notes.
- Don't complain about your job on social media — even vaguely.
- Respect the shared workspace: clean up after yourself, keep noise to a reasonable level.
- Don't gossip. You don't know who's connected to whom.
- Give credit when someone helps you. Say it publicly when appropriate.
- If you make a mistake, own it quickly, explain what happened, and say what you'll do differently.
Building Relationships at Work
Your career will be shaped as much by your relationships as by your skills. In your first 90 days, focus on building genuine connections with your immediate team, understanding what your manager cares about most, and identifying one or two people who have been at the company for a while and are willing to share how things really work. Don't network transactionally — be genuinely interested in the people around you.
How to Ask for a Raise
The best time to negotiate salary is before you accept a job offer — not after you've been in the role for six months. If you're already in a role and want to ask for a raise, document your contributions first: what you've accomplished, the impact it had, and how your responsibilities have grown. Then request a meeting specifically to discuss compensation. Come with a number based on market research, not on what you feel you deserve. Use sites like Glassdoor, LinkedIn Salary, and the Bureau of Labor Statistics to find salary ranges for your role and location.
Your First 90 Days: A Simple Plan
- Days 1–30: Learn the systems, processes, and people. Ask questions. Deliver what's asked of you reliably.
- Days 31–60: Start contributing ideas. Take on a project you can own. Build your reputation for follow-through.
- Days 61–90: Schedule a check-in with your manager. Ask for feedback. Set goals for the next quarter.
