Air traffic controllers in Portugal will stage a series of new partial strikes beginning next week.
The controllers will stop working for two four-hour periods each day beginning on June 29 until July 3. Previous such strikes in April and May severely disrupted air traffic, with hundreds of flights affected.
In addition, pilots working for the state TAP ( Air Portugal) company that is due to be privatised before the end of the year as part of an international bailout, will not fly between July 5-8 and August 1-5.
