Workload
Staffing
If an employee is overworking because their workload is too high then you’ll need to check your staffing levels. Running with the bare minimum of employees may seem like a good cost-saving exercise but it can quickly become expensive when they all start going off sick with stress and you have to find cover at short notice. A good indication of whether staffing is to blame is if the rest of your employees are also overworked; if they are they’re probably being given too much work per shift. If not, there may be another cause.
Availability
Even if you have the perfect number of staff it's useless if they all take leave at the same time. Putting proper leave and unavailability policies in place and making sure that all employees are aware of them will help to prevent this, as well as making sure that your team can see which dates other employees in their section have booked. Managing leave effectively is just as important, though; if leave requests are automatically approved or can be booked last minute then you’ll quickly lose control of your staffing levels. This leaves the remaining employees struggling to cope and working overtime as a result. If possible, try to base holiday approval around your employee schedule and make sure that you have enough staff to cover when a few employees are off at once.
Poor Management
The other thing to look out for when employees are overworked is poor management. If an employee’s manager isn’t managing effectively, or assigns extra work at short notice, employees will work overtime to cope. Make sure that managers are properly trained for their role and that they’re working in line with the company’s values; there’s no point trying to reduce overtime if line managers are telling staff that they’re failing if they take their allotted breaks and leave work on time.
