Starting a new job in the UK: What to do, what to avoid and your workplace rights
Workers’ help and guidance | Starting a new job | UK employment advice
Starting a new job is an exciting opportunity. Whether you are beginning your first job, moving to a new employer or returning to work after a career break, those first few days can shape your confidence, working relationships and future career.
However, starting a new job is about more than making a good first impression. It is also about understanding your employment rights, knowing what your employer expects and recognising when something might not be right.
At The Workers Union, we believe every worker deserves to begin a new job feeling informed, respected and confident.
This practical guide explains what to do before your first day, how to approach your first few weeks, which mistakes to avoid and what UK employment law means for you.
Before your first day: Get the basics right
A successful start begins before you walk through the door.
You should receive clear information about your employment, including your pay, working hours, job responsibilities and where you will be working.
Under UK employment law, employers must provide employees and qualifying workers with a written statement of employment particulars. The principal statement must generally be provided on or before the first day of employment.
Before starting, make sure you understand:
- Your agreed salary or hourly rate and when you will be paid.
- Your normal working hours, shifts and break arrangements.
- Your workplace location and any remote-working expectations.
- Your holiday entitlement and how to request leave.
- Your probationary arrangements, where applicable.
- Your reporting manager and the person responsible for your induction.
What not to do: do not assume that everything discussed during your interview will automatically appear in your employment documents. Check the details carefully and ask for clarification where necessary.

Your first day at work: Make a confident start
Your first day is an opportunity to understand your new environment, meet colleagues and begin building positive professional relationships.
Arrive on time, introduce yourself, listen carefully and take notes when receiving important instructions.
Do not feel pressured to understand everything immediately. Every workplace has different systems, expectations and procedures.
Five things to do on your first day
- Introduce yourself to your manager and immediate colleagues.
- Confirm your responsibilities and priorities for the first week.
- Ask about workplace safety procedures and emergency arrangements.
- Make sure you know how to access essential systems and equipment.
- Find out who to contact when you need assistance.
What not to do: avoid pretending to understand instructions when you are uncertain. Asking sensible questions is a sign of professionalism, not weakness.
Understand your employment rights from day one
Starting a new job does not mean leaving your employment rights at the door.
Depending on your employment status and circumstances, you may have important statutory protections from the beginning of your employment.
These include rights relating to the National Minimum Wage, paid annual leave, protection from unlawful discrimination, workplace health and safety and statutory rest breaks.
Most adult workers are generally entitled to a 20-minute uninterrupted rest break when working more than six hours, subject to applicable exceptions.
Your employer also has legal responsibilities concerning your health and safety. This includes providing appropriate information, instruction, training and supervision.
For authoritative guidance, consult Acas and the Health and Safety Executive.
What not to do: never assume that being new, temporary or on probation means you have no workplace rights.
Probation periods: What every new employee should know
Many employers use probation periods to assess performance, attendance, conduct and suitability for a position.
Probation can also be useful for employees. It gives you an opportunity to decide whether the role, management style and workplace environment meet your expectations.
During probation, make sure you understand how your performance will be assessed, when reviews will take place and whether any additional training is available.
Important: a probation period does not remove statutory employment protections. However, eligibility for certain employment claims and remedies can depend on qualifying service, the reason for dismissal and the law in force at the relevant time.
If concerns arise, ask your manager to explain them clearly and, where appropriate, confirm agreed improvements in writing.
You can also explore our workplace support and guidance if you encounter difficulties during your probation.
Workplace behaviour: The do’s and don’ts
What to do
- Be punctual and reliable.
- Treat everyone with respect.
- Listen and ask questions.
- Follow reasonable instructions.
- Keep important employment records.
- Raise concerns constructively.
What to avoid
- Gossiping about colleagues.
- Sharing confidential information.
- Ignoring safety procedures.
- Making promises you cannot keep.
- Posting workplace disputes online.
- Accepting unsafe practices to impress others.
Your professional reputation develops through consistent behaviour, rather than one impressive first day.
Being helpful, respectful and willing to learn will usually make a stronger impression than attempting to prove you know everything.
What if something feels wrong in your new job?
Occasionally, a new position may not match what was promised during recruitment.
You might discover that your duties are significantly different, your working hours have changed or your manager expects you to work in conditions that cause concern.
If this happens, avoid reacting impulsively.
Start by checking your employment documents and recording the relevant facts. Where appropriate, discuss the issue calmly with your manager or HR department.
If the situation involves discrimination, harassment, unpaid wages or unsafe working conditions, you may need to take further steps.
Read our workplace advice and employee support information to understand how to seek assistance.
What not to do: do not resign in anger without first considering your contractual obligations, financial circumstances and potential employment rights. Leaving employment can have significant legal and practical consequences.
Your first 30 days: Build good working habits
The first month is an important opportunity to establish a positive routine.
Focus on learning your responsibilities, understanding how your organisation operates and developing effective working relationships.
Arrange a discussion with your manager to review your progress and identify any areas where you need additional support.
You should also check that your first payslip is correct, including your pay, deductions and hours where applicable.
If your employer offers training, take advantage of it. Learning new skills can improve your confidence and future career opportunities.
Remember that success in a new job is not about working excessive hours or accepting unreasonable demands. It is about contributing effectively while maintaining healthy professional boundaries.

Starting a new job should be a positive experience
Every new job comes with challenges, unfamiliar responsibilities and opportunities to learn.

Preparation, communication, professionalism and an understanding of your rights can make the transition significantly easier.

Start your new job with confidence. Understand your rights, respect your responsibilities and never be afraid to ask for help.
Frequently asked questions about starting a new job
Yes. Employees can make a statutory flexible-working request from their first day of employment. Employers must consider requests in accordance with the applicable legal requirements.
If your request has been rejected, read our guide to refused flexible-working requests.
Yes, dismissal can occur during probation, but employers must still comply with applicable employment law, contractual obligations and statutory protections. The qualifying period for ordinary unfair dismissal protection is changing, so the date and circumstances of dismissal matter.
Ask your employer for your written statement of employment particulars. The principal statement is required by the first day, with certain additional information provided within two months.
Inform the appropriate person, explain what happened and ask how to correct the problem. Concealing mistakes can create more serious difficulties than acknowledging them.
