The decision to call the strike follows a period of negotiations with the management of the Canarian Health Service (SCS) which, despite a promising start in February, has reached a "dead end." According to a union spokesperson in Las Palmas, the administration has shown a delaying attitude towards the proposals submitted.

The union established "red lines" at a meeting on April 6 and gave a one-week deadline for a response, but the lack of reply led to the call for strikes. The hope is that the Ministry of Health will resume dialogue to avoid, at least, the strike day on May 4.

Among the main demands is the regulation of on-call hours, which in the Canary Islands are the "worst paid in all of Spain," even below the value of a regular working hour. The goal is to improve contractual and remuneration conditions to make the SCS more competitive and curb the exodus of professionals to other communities, private healthcare, or European countries, a situation that has led to a "doctor deficit" in islands such as Fuerteventura, La Gomera, and La Palma.

The discontent also extends to the non-compliance with agreements signed in 2023 with the previous government, whose economic allocations, although budgeted, have not been executed. The union suspects that this delay is a strategy to avoid fulfilling what was agreed. Furthermore, they have denounced "abusive minimum services" imposed by some hospital managements, filing a complaint with the Labor Inspectorate for what they consider an "excessive and restrictive interpretation" of the regulations.
