Scottish ministers are considering action against employers for docking the wages of staff who could not make it to work because of the bad weather.
The public was advised not to travel during the worst of the snow last week.
Scottish Transport Minister Humza Yousaf said he had been contacted by people who were facing disciplinary action or potential docking of wages.
He told the BBC that was not acceptable and he would look at the legal position.
The west coast mainline reopened between Scotland and Carlisle on Sunday evening.
ScotRail earlier said it had a “near-normal service” running across the country.
Many rural communities in south-west England which had been cut off by poor conditions can now be reached.
Workers ‘facing disciplinary action’
On Wednesday into Thursday, Scotland ground to a halt with a red weather warning in place and people told not to travel unless absolutely necessary.
Speaking on the BBC’s Sunday Politics Scotland programme, Mr Yousaf said: “I’d be extremely, extremely disappointed if employers chose to dock wages for somebody because they couldn’t travel during the red weather warning.”
