LISBON, April 8 (Reuters) - Boavista players will begin a strike next week if the Portuguese Premier League club does not pay wages that are two months late, the head of the players' union said on Tuesday.
If they strike, the players would skip a league match against Nacional Madeira on April 20.
Similar strikes could also take place at other Portuguese clubs that are struggling to meet their financial obligations to players, the head of the Professional Soccer Player's Union Joaquim Evangelista said.
'Boavista players unanimously decided to formalise a strike if the players do not receive their pay cheques by Friday,' he told reporters.
The Boavista strike would not take place immediately because under Portuguese law workers must issue a warning five days before they strike.
That means Boavista would still travel to Vitoria Guimaraes this weekend before missing the Madeira match the following weekend.
The players are claiming wages from February and March, plus 70 percent of their December salary.
Boavista, the subject of an investigation by the Portuguese league into match-fixing relating to the 2003-04 season, said in a statement it understood the players' demands and that it was doing all it could to resolve the situation.
Boavista, who drew 0-0 with Benfica on Sunday are 10th in the league. Porto have already won the title.
