It is unfair for unions to "disrupt people's lives" with public-sector strikes at Christmas, Conservative chairman Nadhim Zahawi has said.
He said plans were in place to draft in the military to drive ambulances and secure borders if walkouts went ahead.
Mr Zahawi also told the BBC Russian President Vladimir Putin "wants to see" strikes, but unions criticised this.
Thousands of workers from various industries are set to strike this month in disputes over pay and conditions.
Some unions say pay should match the cost of living, which is increasing at its fastest rate in 40 years, largely as a result of rising food and energy prices.
Some of the most high-profile strikes have been called by unions representing workers in the NHS, the railways and the Royal Mail.
Nurses in England, Wales and Northern Ireland will strike over two days this month, in what is set to be their biggest walkout in the NHS's history.
Elsewhere,
rail strikes will be held across four 48-hour periods in December and January, leaving passengers facing severe disruption to Christmas travel.
In an interview on the BBC's Sunday with Laura Kuenssberg programme, Mr Zahawi was asked what the government was doing to end the strikes.
The minister said President Putin's war in Ukraine - which has sent energy costs soaring - was the main driver of rising prices and pressure on pay.
He suggested some of the pay rises demanded would further stroke inflation - which is the increase in the price of something over time - which would "hurt the most vulnerable".
The government has repeatedly urged unions and employers to negotiate settlements and halt strike action, saying it can not afford pay rises to cover inflation.
But unions say workers have faced real-terms cuts to pay over many years and deserve a fair deal that reflects the current cost of living.
