Are you unintentionally harassing them by trying to find out where they are? Are you concerned that something might have happened to them? There's a fine line between being a responsible employer, coming across as overbearing and not wanting to compromise the working relationship with your employee.
It is important for you to know that as a responsible employer you do have a duty of care to ensure that under the Health & Safety at Work Act 1974 which states that "it shall be the duty of every employer to ensure, so far as is reasonably practicable, the health, safety and welfare at work of all his employees".
What this means is if an employee doesn't turn up for work that in the interests of their health & safety, and in line with their contractual obligation to their employer, the employer has a duty of care to check whether they will be coming into work. After all, how do you know that the employee hasn't been involved in a car accident?
On checking whether an employee is coming into work, and their reason is purely that they are either running late or they are feeling sick, to make them aware of your reporting procedure which is normally provided within an Attendance Policy which would address both sickness and lateness reporting.
So what if you can't make contact with the employee? Well the first step would be to leave a voicemail message for the employee advising them that you are concerned about their whereabouts and asking them to return your call asap?
What if you still haven't heard from the employee by Day 2? We would suggest that you write to the employee a letter of concern asking them to contact you, giving them a date by which you expect a response.
If you still don't receive a response by the requested date, then you would be well within your rights to initiate disciplinary proceedings in the normal way.
You balance your time between being in the business and running the operation, and out of the business and thinking about how you want your business to grow and how you can make your business as efficient as possible. The one key question that is vitally important and will make the difference between whether you achieve your goals or not is what a model employee would look like to you.
Are you sure you’ve covered all the why’s and wherefore’s and how you’ll nurture your newbie in the first few weeks of employment with you? It's really easy to make assumptions that because a new employee may have the skillset that you are looking for to jump to conclusions, hoping that it will all work out fine. It’s almost guaranteed that they’ll have superficial knowledge of who you are and how you do things.
