The walkout, which the organizers have dubbed "Pharmageddon", is the third strike by pharmacists in a little over one month.
In September, some staff from CVS stores in Kansas City went on a two-day strike, while there was another by Walgreens store employees earlier this month.
Pharmacy staff in New York and Pennsylvania were planning to participate, including workers at some of Walgreens' Duane Reade stores in New York, he said.
Some pharmacists were also planning to conduct rallies outside CVS' headquarters at Woonsocket, Rhode Island and at Walgreens at Deerfield, Illinois, according to social media posts.
"Our ongoing efforts are focused on how we recruit, retain, and reward our pharmacy staff," a spokesperson for Walgreens told Reuters, adding that they have also centralized some operations to reduce pharmacists' workload.
