A man has been charged with criminal damage after an incident at the National Gallery in London last week.
A protester linked to the Fathers4Justice campaign group is alleged to have stuck a photograph on Constable's masterpiece The Hay Wain last Friday.
A spokeswoman for the gallery said conservation staff were on the scene quickly and the painting was removed for treatment. The picture went back on display on Friday night.
A spokesman for PCS, the Public and Commercial Service union, said it had previously alerted museums and galleries to the dangers of cutting back on front of house staff: "We warned, before the more serious attack on the Poussin piece in 2011 and since, that it was wrong to cut the number of warders at the National Gallery.
"Thankfully, The Hay Wain was not seriously damaged, but we hope the gallery management is serious when it says it will review security arrangements."
In a statement Fathers4Justice said that it was abandoning five-year long political campaign and called on fathers to take independent weekly direct action “in an attempt to defend themselves and the 1,000 families a week destroyed in the secret family courts”.
The group called for fathers to follow the footsteps of the Suffragettes.
The incident happened as another Fathers4Justice campaigner appeared in court last week accused of vandalising a portrait of the Queen in Westminster Abbey.
