Hundreds of Auckland health workers are expected to strike on Friday, saying they are understaffed and overworked.
The union for allied health workers, the PSA, put up cut-out silhouettes outside Auckland City Hospital today as part of the protest.
It said they represented 642 staff planned for by Auckland's three DHBs this year - but not employed.
PSA spokesman Andy Colwell said its workers will strike for four hours from 10am on Friday over working conditions, and the DHBs' plans to extend five day services to seven days.
"That is going to compromise services, it is going to stretch workers to breaking point, where people will leave, people will take sick leave, people won't be able to work, and we'll be more understaffed."
A DHB spokesman said they could not comment because the two sides were meeting to try to resolve the dispute.
