The Greek government is beginning a new round of talks with creditors sceptical about the depth and effectiveness of its pension reform plans amid widespread protests over the proposals.
Talks with the quartet of creditors - the European Commission, the European Central Bank, the European Stability Mechanism and the International Monetary Fund - are resuming on Monday.
The government says the first phase of the talks will last a week and, following a short break, will reconvene until the completion of the first assessment of Greece's third bailout deal, signed last August.
Strikes against the pension plan are planned through most of the week: transport workers on Tuesday, journalists on Wednesday, a general strike Thursday, and transport shipping crews on Friday.
Meanwhile, farmers are continuing intermittent road blockades across Greece.
Farmers used scores of tractors to indefinitely block two border crossings with Turkey and Bulgaria, stopping lorries but allowing all other traffic to pass.
Other crossings with Turkey and Bulgaria were being sporadically closed, as were motorways across Greece.
