Livingston boss David Martindale believes the Scottish Premiership would benefit from full-time referees after receiving another apology for his side missing out on a penalty.
Martindale revealed that Scottish FA head of referees Willie Collum had been in touch to discuss the denial of spot kick late in Saturday's 1-1 draw at home to Kilmarnock.
Brad Lyons appeared to stick out an elbow to deflect the ball away from goal, but referee Don Robertson took no action and there was no stoppage in play to review the incident.
Collum made a similar call to Martindale in the wake of an unpunished handball from Rangers defender Emmanuel Fernandez during a 2-1 defeat at Ibrox in November.
"Very, very similar to Ibrox, if I'm honest," said Martindale.
"But I don't think it's a Willie Collum problem. I don't think it's just an official's problem. I think it's a Scottish football problem.
"We need to get our heads together and we need to find solutions very quickly.
"I appreciate Willie phoning, I really do. But it's not really worth anything at the end of the day because I've been through this, what, eight weeks ago?
"I'm now going through it again. And it's really hard to get your head around. I think we've got to do better."
Scottish officials are paid by game on a part-time basis, while Collum said last month there is no handball problem this season
"If you were to go with a full-time team and a part-time team, over the course of a season, the full-time team's going to make better decisions," said Martindale.
"They're going to be fitter, they're going to be stronger, because that's their full-time focus. I think we need to start phasing the double jobs.
"There's a lot of referees that are very intelligent individuals within their own industries. They're in good jobs and I understand it would be hard for that transition into full-time football because you'd probably lose a lot of household turnover.
"But I think we've got to start phasing that in. I know the salaries on offer for referees and there'd be a lot of people who'd bite your hand off for that in a full-time position.
"It's the only way it's going to get better, is by having it full-time."
