A quarter of Londoners feel lonely at work and the average spends 13 hours a week without having a single conversation, new research shows.
Only 12 per cent admit to phoning a partner once a day from their job - and more than half say they’d only call in an emergency.
A typical person last called their other half on the phone 13 days ago, preferring texts instead.
London’s van drivers are among the most impacted professions suffering from loneliness and mental health issues.
Also on the list are those working in charity, banking, legal, healthcare, tech, sales, government, tradesmen and women, social care and agriculture.
The trend is being driven by people working from home, according to an Opinium survey for Mercedes-Benz Vans of 2,000 UK workers on Time To Talk Day.
It reveals that calling or checking in on a loved one and sharing a tea break with a teammate are among the biggest benefits of good wellbeing at work.
Yet less than 43 per cent are stopping to have a chat with a colleague.

The capital (27 per cent) is only beaten by Yorkshire and Humberside (28 per cent) for employees who feel lonely at work.
East of England (21 per cent) and the South East (20 per cent) were third and fifth in a list.
Iain Forsyth, managing director of Mercedes-Benz Vans UK said: “A single meaningful conversation can have a huge impact on someone’s mental wellbeing, especially if they’re spending long hours at work alone.
“To support Time To Talk Day, Mercedes-Benz Vans in the UK will be encouraging colleagues to take a break, a walk or reach out to a loved one, friend or colleague to check in.”
Time to Talk Day is supported by Mind and Rethink Mental Illness.
