The three-day campaign in the Khyber tribal district is due to start tomorrow, almost three weeks after gunmen shot dead a worker while he was administering polio drops and vaccines to children in the town of Jamrud.
Efforts to stamp out the crippling disease in Pakistan have been seriously hampered by militant attacks on health workers inoculating children.
The Pakistani Taliban banned polio vaccinations in the tribal region of Waziristan in 2012, alleging the campaign was a cover for espionage.
He said these employees recently held talks with the local administration and demanded better security and higher wages for health workers.

He said the campaign would be launched according to schedule in Bara and Landi Kotal towns of Khyber from Saturday.
"If the health workers do not participate in the campaign in Jamrud, we will hire the local tribal police for the purpose," the official added.
"Our lives are dear to us and we have decided not to join the campaign," he said, asking not to be named.
Pakistan is one of three countries in the world where polio remains endemic, along with Afghanistan and Nigeria.
Eradication efforts have also suffered due to long-standing rumours that the vaccine was part of a Western plot to sterilise Muslims.
According to the World Health Organisation, Pakistan recorded 85 cases of polio last year compared with 58 in 2012.
