Porters at Ninewells Hospital staged a fresh walkout on Friday in their dispute over pay.
They downed tools and formed a picket line on Ninewells Avenue and will stage another walkout on Monday unless a deal is reached with NHS Tayside.
The porters claim NHS Tayside owe £6 million in pay from the last decade because of an administrative issue that is said to have left them in the wrong pay bracket.
Richard Murray claimed Ninewells porters are paid less than those doing the same job elsewhere in Tayside.
The porter said: “This is a legal strike, we’ve gone through all the proper channels and all NHS Tayside has done is come back with threats.
“We just want them to do the right thing. All we are asking for is the same thing every other porter in Scotland and Tayside gets.”
The porters will take their protest to Scottish Government health secretary Shona Robison’s office on Old Glamis Road on Friday afternoon.
They will march from Fairmuir Park to her office at 12 noon.
