Hundreds of workers who deliver food to Burger King, KFC, Pizza Hut and Wagamama have backed a strike over pay that will threaten supplies.
The GMB union said the majority of members employed by Bestfood who took part in the ballot were in favour of industrial action.
Strike dates will be announced soon.
National officer Nadine Houghton said: ‘The parent companies of Bestfood – Booker and Tesco – are making serious money.
‘Shareholders are trousering large dividends, while the people who do the graft are struggling to make ends meet.
‘All these workers want is a pay deal that protects them from this crushing cost of living crisis.
‘Now some of the best-known restaurants on the UK’s high streets will face shortages over Christmas.’
Bestfood drivers who deliver to Pizza Express and Zizzi are reportedly also expected to announce strike dates.
Staff at Greene King have also followed suit and voted for industrial action.
The latest strikes follow an announcement over further walkouts by transport staff.
The four 48-hour actions on December 13/14 and 16/17 and January 3/4 and 6/7 will be made worse for families, workers and party-goers by an overtime ban from December 18 to January 2 – and engineering works from December 23 to January 3.
Mr Lynch said: ‘I’m not the Grinch – I’m a trade union official and I’m determined to get a deal.’
In London, TfL has also said that Abellio bus services will be affected by strikes soon.
The industrial action will mainly affect services in west and south London.
Currently, staff are in a pay dispute with Royal Mail, with the CWU demanding a raise that ‘addresses the cost of living’ – while the company says it has offered workers a ‘pay-for-change’ deal ‘worth 9% over two years’.
There is also a dispute over worker conditions and the ‘Uberisation of Royal Mail’, says the union.
