The last of a number of threats of industrial action potentially affecting air services was averted on Friday when the sides gave their approval to a mediation proposal put forward by National Conciliator Esa lonka.
The action, which was to have started on Sunday night, would have affected more than 70 people employed in the technical services of air traffic control.
The settlement was reached nearly two weeks after a dispute with air traffic controllers themselves was settled.
The planned five-day strike might have caused delays in repairs of technical equipment used by air traffic control.
Disagreements included questions of terms of employment, as well as which of various contracts in the field applied to this particular group of employees.
Later in the autumn the contracts of a number of other groups of aviation staff are to come up for negotiation.
