10 Rules for Hospitality Group Chats

When did joining a kitchen brigade also mean handing your employer access to your personal phone — 24 hours a day?

WhatsApp has become part of everyday hospitality life.

Kitchen rotas are posted on it. Shift changes are arranged through it. Photographs of prep are shared. Managers send instructions. Chefs arrange cover. Questions are asked about stock, deliveries, bookings and tomorrow's mise en place.

Used properly, a WhatsApp group can be useful.

Used badly, it can turn an employee's personal mobile phone into an extension of the workplace — one that follows them home at the end of every shift.

At Unichef, The National Chefs Union, we are increasingly hearing from chefs who either don't want to join workplace WhatsApp groups or feel unable to escape from them once they have.

So where should the boundaries be?

Here are our 10 Rules for Hospitality WhatsApp Groups.

1. Joining a WhatsApp group should not mean being permanently on duty

A chef finishes work.

They clock out, get changed and go home.

That should normally mean work has finished.

It should not mean:

10:45pm: “Who's opening tomorrow?”

11:10pm: “Has anyone ordered the salmon?”

11:35pm: “Can somebody send me the figures?”

6:15am: “Why haven't you replied?”

There is currently no standalone statutory UK right to disconnect from work outside contracted hours. The Government has previously committed to introducing a Right to Switch Off through a statutory Code of Practice, but as of August 2026 that code has not yet created a general legal right to ignore every out-of-hours communication.

But employers should not confuse the absence of a specific “WhatsApp law” with permission to treat employees as permanently available.

Government guidance already says that working time can include unpaid overtime which an employer asks somebody to perform.

UNICHEF RULE: If a message can wait until the employee's next shift, let it wait.

2. A personal phone is still a personal phone

Most hospitality WhatsApp groups operate on employees' own mobile phones, using their own telephone numbers, their own data and their own WhatsApp accounts.

That matters.

An employer may reasonably need a method of communicating with its workforce.

That does not automatically mean the employer can insist that every employee turns their private telephone and private WhatsApp account into the company's communications system.

If WhatsApp is essential to the operation, employers should consider whether an official system, work device, rota app, email account or alternative communication method should be available.

The Information Commissioner's Office warns that using workers' own devices for company business creates additional privacy and security risks and says organisations should assess and manage those risks.

UNICHEF RULE: Employers can reasonably expect communication. They should not automatically expect ownership of the employee's personal device.

3. Nobody should be disadvantaged simply because they do not want WhatsApp

Not everyone wants WhatsApp.

Not everyone owns a smartphone.

Some people deliberately keep social media and messaging apps away from work.

Others may have accessibility, privacy, religious, family or personal reasons for not wanting their mobile number circulated among colleagues.

An employer therefore needs to think very carefully before declaring:

“Everybody MUST be in the WhatsApp group.”

There is no simple law stating that an employee can always refuse every workplace messaging system.

If an employer has a legitimate and reasonable communication requirement, employees may be expected to cooperate with reasonable workplace arrangements.

But there is a considerable difference between:

“You must remain contactable by the company.”

and:

“You must install this particular application on your personal telephone, give your private number to your colleagues and monitor it outside work.”

Where a reasonable alternative is available, Unichef believes employers should provide one.

UNICHEF RULE: No employee should be isolated from essential workplace information because they decline to participate in a personal WhatsApp group.

4. Rotas and shift changes need proper confirmation

This is one of the biggest problems in hospitality.

A manager posts:

“New rota guys.”

Twenty-seven messages follow.

Someone sends a joke.

Someone asks about Saturday.

Someone posts a photograph.

The rota disappears halfway up the conversation.

Then three days later:

“You were supposed to be in at 7.”

Critical information such as scheduled working hours should not depend upon whether somebody happened to scroll through 83 WhatsApp messages while they were off duty.

The Employment Rights Act 2025 also now expressly recognises that employers may make shift requests to multiple workers through a group text message or app in the context of the new shift-notice provisions. That is another indication of just how significant digital group communications have become in modern employment.

UNICHEF RULE: Rotas and compulsory shift changes should be issued through a clearly identified official system, and significant changes should be directly confirmed with the employee concerned.

A blue tick should not replace proper management.

5. Do not conduct disciplinary management through WhatsApp

This should be obvious.

Unfortunately, it isn't.

Messages such as:

“Who left this mess?”

“This is unacceptable.”

“John, explain yourself.”

“If you can't manage your section we'll find someone who can.”

have no place in a group containing someone's colleagues.

Performance concerns should be dealt with privately, professionally and through the employer's proper procedures.

Group humiliation is not performance management.

Nor should WhatsApp become a substitute for investigations, grievance meetings, return-to-work discussions or disciplinary processes.

Managers should also remember something incredibly important:

WhatsApp messages can become evidence.

A comment written casually at 11pm can later appear in a grievance, subject access request or Employment Tribunal bundle.

UNICHEF RULE: Praise publicly if appropriate. Manage problems privately.

6. Never discuss an employee's sickness or medical condition in the group

This is particularly serious.

Messages such as:

“Jane is off with anxiety again.”

“Pete's back is playing up.”

“Sarah has another hospital appointment.”

should not be casually circulated among an entire kitchen brigade.

Health information can constitute special category personal data, which receives additional protection under UK data protection law.

The ICO specifically warns employers that workplace monitoring and communications can capture particularly sensitive information, including health information, and that such information requires additional protection.

The team may need to know:

“Jane will not be working tonight.”

They generally do not need Jane's medical history.

UNICHEF RULE: Absence can be communicated. The reason for somebody's absence usually does not need to be.

7. Don't turn WhatsApp into unpaid administration

One message takes thirty seconds.

Another takes two minutes.

Then:

“Can everyone check tomorrow's function sheet?”

“Please confirm you've read the new allergen procedure.”

“Can all chefs send me their availability?”

“Watch this training video before tomorrow.”

“Send your stock requirements tonight.”

Individually these can look insignificant.

Collectively they can become substantial amounts of work performed outside someone's paid shift.

Government working-time guidance includes unpaid overtime an employer asks somebody to perform when calculating working hours.

National Minimum Wage rules also look at the reality of whether work is actually being performed, rather than simply what an employer calls it. HMRC guidance on on-call arrangements makes clear that where somebody is at home, waiting alone will not normally count for minimum-wage purposes — but actual work performed can change the position.

There will inevitably be occasional brief communications in hospitality.

But if staff are regularly required to perform administrative tasks from home, employers need to stop pretending that this activity somehow ceases to be work because it happens on WhatsApp.

UNICHEF RULE: Required work should be done in working time.

8. Respect the chef's statutory rest

Hospitality already has a long-hours problem.

Chefs commonly finish late and return early.

The Working Time rules generally give adult workers a right to 11 consecutive hours' daily rest between working days, subject to exceptions and compensatory-rest provisions in particular circumstances.

So consider the culture created when a chef finishes at 10pm and receives management messages at:

10:30pm.

11:15pm.

Midnight.

6am.

Even where simply receiving a message does not itself automatically interrupt statutory rest, a workplace culture requiring employees to read, engage with and respond to work throughout their rest period deserves very serious scrutiny.

Rest is not laziness.

It is part of safe working.

And in a commercial kitchen, where employees work with knives, boiling liquids, heavy equipment, machinery, flames and extreme temperatures, fatigue matters.

UNICHEF RULE: Off duty should genuinely mean off duty.

9. Workplace group chats need the same standards as the workplace

WhatsApp is not a legal-free zone.

Comments that would be unacceptable standing at the pass do not suddenly become acceptable because somebody adds a laughing emoji.

Employers should make clear that workplace messaging policies cover:

• bullying;

• sexual harassment;

• discriminatory comments;

• racist, sexist, homophobic or ableist material;

• threatening behaviour;

• inappropriate photographs;

• gossip about colleagues;

• sharing confidential information; and

• targeting or excluding individuals.

The casual nature of WhatsApp can encourage people to type something they would never dream of putting into an email headed:

“Dear Human Resources...”

Employees should assume that anything written in a workplace group could eventually be read by management, HR, a union representative, a solicitor or an Employment Tribunal.

That thought alone would improve many kitchen group chats enormously.

UNICHEF RULE: If you wouldn't say it formally at work, don't put it in the work WhatsApp group.

10. Every employer should have a Workplace Messaging Policy

This is perhaps the most important rule.

Hospitality businesses have policies for:

food hygiene;

uniform;

absence;

holidays;

discipline;

health and safety;

allergens;

social media.

Yet many have absolutely no policy governing a communications channel that their managers and employees may use hundreds of times every week.

That needs to change.

A sensible workplace messaging policy should establish:

• whether membership is compulsory or optional;

• what the group is actually for;

• what information must never be shared;

• expected communication hours;

• whether out-of-hours responses are required;

• how urgent communications will be identified;

• how rotas and shift changes are formally confirmed;

• alternative arrangements for employees who do not use WhatsApp;

• rules on bullying, harassment and inappropriate content;

• management responsibilities;

• data protection arrangements;

• how employees leave groups when employment ends; and

• where formal HR matters should be communicated instead.

The ICO says employers must consider privacy when using monitoring and communication technologies, be transparent with workers and ensure processing of workers' information is lawful, fair and proportionate.

A properly written policy protects employers as well as employees.

WhatsApp Is a Tool — Not a Workplace

Unichef is not arguing that hospitality should stop using WhatsApp.

That would be unrealistic.

Used sensibly, it can be quick, convenient and extremely useful.

What we are saying is that boundaries matter.

A chef selling eight or ten hours of their labour to an employer has not automatically sold the remaining sixteen hours of their day as well.

Their personal telephone does not become company property.

Their evening does not become an unpaid extension of the shift.

Their medical information does not belong in the kitchen group.

And their failure to respond instantly to a message while spending time with their family should not automatically become a question of commitment.

Technology has changed the way hospitality communicates.

Employment standards need to catch up.

The Unichef Principle

Employers have a legitimate right to communicate with their workforce.

Employees have a legitimate right to privacy, rest and a life outside the workplace.

Good management respects both.

WhatsApp isn't the workplace.

And being employed shouldn't mean being permanently online.
