Hundreds of employees of the Eastern Cape health department have been issued with final warnings aft.
"Every day and every weekend there are hundreds of thousands of players travelling in cars, buses, trains and planes... they are always exposed to this risk of accidents," said La Liga president Javier Tebas yesterday.
"We want to recognise, remember and offer our condolences to the families."
A minute's silence will also be held before all matches in the Copa del Rey across Spain today.
Madrid, Barca and Atletico Madrid were among a host of Spanish clubs to express shock and sadness at the plane crash in Colombia on Tuesday.
Former Atletico midfielder Cleber Santana was one of those killed as the plane went down just before reaching its destination in Medellin, where Chapecoense were to play in a Copa Sudamericana final.
Six people miraculously survived the crash.
Three of the survivors were footballers, but goalkeeper Jackson Follmann had his right leg amputated, said the San Vicente Foundation Hospital outside Medellin.
Two flight crew and a journalist following Chapecoense for the game against Medellin also escaped.
Brazil ordered three days of national mourning for the team.
Fans flocked to the Chapecoense Stadium in Brazil to mourn the team, who have emerged from nowhere over the past two years to take South American football by storm.
Other Brazilian clubs have offered them players so they can carry on competing. Special funds have also been set up.
Football legends Pele and Maradona and current superstars Lionel Messi and Cristiano Ronaldo led tributes to the Chapecoense team.
