BRUSSELS (Reuters) - Italian pilots for Ryanair will join a cabin crew strike across five countries on Sept. 28 and unions may continue with industrial action once a month until they win changes to labor contracts, cabin crew unions said on Thursday.

“Pilots in Italy will strike together with cabin crew,” said a spokeswoman from the UILTRASPORTI union.

However, the unions told a joint news conference they were willing to reconsider their industrial action if changes to the airline’s employment model were announced at a shareholders meeting on Sept. 20.
