Why Onboarding Matters
Research consistently shows that employees who experience structured onboarding are significantly more likely to stay with the organisation beyond their first year. Poor onboarding is one of the top reasons for early turnover, and replacing an employee typically costs between 50% and 200% of their annual salary.
In the UK, effective onboarding also has legal significance. Employers must complete right-to-work checks before the employee's first day of work, and a written statement of employment particulars must be provided on or before the start date.

Frequently Asked Questions
When must a right-to-work check be completed?
A right-to-work check must be completed before the employee's first day of work. It is a criminal offence to employ someone who does not have the right to work in the UK, and failing to conduct the check removes your statutory excuse against a civil penalty.
How long should onboarding last?
Best practice suggests onboarding should span at least the full probation period, typically 3-6 months. The first 90 days are the most critical for engagement and retention. Even a well-structured first week is insufficient on its own.
What is a written statement of employment particulars?
Under the Employment Rights Act 1996 (as amended), employers must provide a written statement on or before the employee's first day. It must include key terms such as job title, pay, hours, holiday entitlement, notice periods, and pension arrangements.
