Nieminen said the possible support measures will fall at around 19-27 November, the period when PAU is scheduled to undertake the industrial action.
The transport unions have demanded that Posti should stop using temporary workers.
According to Nieminen, each transport union will decide an industrial action on its own and report the content of the measure in due course.
The Service Sector Employers’ Association (Palta) and PAU are scheduled to continue negotiations today (Tuesday) with National Conciliator Minna Helle.
