(Portland, OR) -- Employees from all three Powell's Books locations around Portland rallied downtown yesterday as part of a planned one-day strike. It's the first strike for Powell's employees in 20 years, and comes after months of contract negotiations have stalled. Workers are asking for affordable health care and a living wage. The book shop's owner, Emily Powell, says Powell's is committed to reaching an agreement that's "sustainable and fair." Stores are expected to open again today, but union reps say employees are ready to strike again if adequate terms aren't reached.
