Football fixtures in Scotland face possible postponement next weekend after the top referees voted to strike.
Scottish match officials are upset with the avalanche of flak that has come their way this season.
BBC Scotland has learned that officials are concerned that their integrity is constantly being questioned by some clubs and individuals.
And there are increasing fears among referees over personal safety as a result of public criticism.
The decision to take strike action was reached at a referees' union meeting, with unanimous backing.
There are six Scottish Premier League games scheduled for next weekend along with a full card in the Scottish Football League.
Celtic have voiced concerns about refereeing standards this season and last and BBC Scotland has also learned that the Glasgow club would welcome the strike.
It is understood Celtic hope that it could lead to a wider independent investigation and want Uefa to intervene in what they think is a refereeing crisis.
