They come after pay cuts and tax hikes this year have fueled growing discontent at a time of deep recession and record unemployment of 15.9 percent.

Rail services were at a virtual standstill Thursday due to a strike by engineers. The Lisbon subway also closed during the morning rush-hour due to a walkout, while suburban bus services were also disrupted.
