Unless you have contractually promised to provide transport for employees to and from their place of work, the onus is on the employees to get to work regardless of the severity of the weather conditions.
The responsibility for employees getting to work does not lie with you, the employer. If employees fail to turn up for work in these circumstances, you are under no obligation to pay them. If an employee’s normal mode of transport cannot be used because of disruption due to severe weather conditions you should first encourage the employee to explore alternative means of safe transport. You may wish to consider whether the employee could usefully work from home until the weather situation has improved. Before you do this you need to agree what the employee is working on so that they have some deliverables. If this is not a viable option, then the alternatives available are for you to advise employees that any time off work in these circumstances will be unpaid, or paid on a discretionary basis but only in exceptional cases. Another option is that employees can request to take the time off as paid annual leave.
