Around 58 union members at the 200-staff company began a series of planned walk-outs on 21 November after management made changes to contractual holiday terms without discussion or prior notice.
Employees at the £20m-turnover company are entitled to up to five 'floating' holiday days a year, depending on their employment contracts, which they can take at any time of year outside of fixed holiday periods during seasonal closures.
Strike action was mooted after the company extended the number of fixed days holiday that staff were expected to take over Easter while the number of floating days was reduced.
Unite regional co-ordinating officer Colin Cooper said that the floating days were a vital part of employees’ contracts as it allowed them a certain amount of freedom and work-life balance.
This morning, following a series of meetings between management and union members yesterday, the company has agreed to reinstate the floating holiday days
Cooper said: "The floating holidays that allow people to have a good work life balance have been restored and secured. The company has agreed that no changes will be made in future without prior negotiation and agreement. That is key.
"There were a lot of feelings of insecurity. But we have agreed that there will be a full review in 12-months to ensure that things are still running smoothly and that the agreement is still in place."
Smith Anderson chief executive Michael Longstaffe said: "I am thrilled to have seen such a swift resolution when common sense prevailed and we can get back to doing what we all do best, especially during the week before Christmas."
He added: "Smith Anderson has enjoyed a three-year period of sustained and profitable growth and although this action did not affect customer service in any way, the influence on morale was most painful."
"We will now power into 2013 with renewed energy and as a united force, fully relocating to our new state of the art premises in Kirkcaldy before the summer of next year," Longstaffe said.
