Description

From the listing uploaded by “appupdater”.

This app is for the members of Finnish Cabin Crew Association SLSY ry. SLSY app is our official member app and is an advanced tool in our communication and interaction with our members. It is technically provided by an Icelandic 2Way technology company. Modules in this app include possibilities to share news, documents, event information, and work-related data, with few easy steps from the back end system. Survey results, destination hotel quality, and contacts can be easily checked. Important information can be relayed as push notification. Members can update their member data directly, and membership verification is guaranteed. We look forward to adding new features in this app and working together with 2Way. SLSY is an independent registered branch of the Finnish Transport Workers Union (AKT ry). Our umbrella of worker representation is based on the Collective Labor Agreement (CLA) for Cabin Crew Members in Finland.
