Probation Period
An initial employment period (typically 30-90 days) during which a new employee's performance and fit are evaluated, often with reduced job protections or easier termination procedures for the employer. Common globally; less formalized in the US.
A probation period (also called a trial period or introductory period) is a defined period at the start of employment — typically 30, 60, or 90 days — during which the employment relationship is considered provisional. **What it means in practice:** - The employer evaluates whether the new hire is meeting performance expectations - In some jurisdictions, termination during probation is simpler (no cause required; reduced severance) - In the US, at-will employment already gives employers this flexibility, making formal probationary periods less legally significant than in countries with stronger employee protections - Benefits may be delayed until after the probationary period (health insurance effective at 90 days, for example) **International context:** In EU countries, UK, Australia, and elsewhere, employees often have legal protections against wrongful dismissal after a certain tenure. Probationary periods typically exempt the employer from these protections for the defined initial period. **US implications:** - Most US employment is at-will, so a probationary period doesn't dramatically change legal rights - Practical implication: performance is actively evaluated and documented during this period - It can affect benefits timing (health insurance, 401k eligibility, PTO accrual starting point) **For candidates:** Understand what happens at the end of the probationary period: Is there a formal review? Are benefits or pay changes contingent on passing? Is the period extendable? **Performance expectations:** A 90-day plan — explicit agreement on what success looks like in the first 90 days — is invaluable for navigating a probationary period successfully.
Why it matters
Losing a job during a probationary period before new benefits have kicked in can leave you with a gap in health coverage and without the tenure needed for unemployment insurance in some states. Understanding what the period means practically matters.
Candidate tip
In your first week, ask your manager directly: 'What would success look like at the 90-day mark, and how will you evaluate performance during the onboarding period?' — explicit criteria remove ambiguity and set you up for a successful review.

Employment Contract
Offers & NegotiationA legally binding agreement between employer and employee that specifies the terms of employment — compensation, role, duration (if fixed), termination conditions, and any special provisions. More common for executives, contractors, and international hires than for general US employees.
Onboarding
Offers & NegotiationThe process of integrating a new employee into a company — covering orientation, training, systems access, team introductions, and role-specific ramp-up. Good onboarding dramatically affects first-year retention and time-to-productivity.
At-Will Employment
Offers & NegotiationThe legal default in the US where either party — employer or employee — can terminate the employment relationship at any time, for any reason (with some legal exceptions). Most US jobs are at-will unless a contract specifies otherwise.
Notice Period
Offers & NegotiationThe time between giving notice that you're leaving a job and your last day of work. In the US, two weeks is the professional standard. In some European countries, 1-3 months is legally required. Some roles have contractual notice requirements.
