A survey of 200 HRDs by recruiter OfficeTeam found more than a third (37%) say that the line manager assumes responsibility.
The vast majority (85%) of employers do not bring in extra staff to cover the shortfall in resources, expecting their teams to share the work between them.
The research reveals while there are a number of ways to manage workloads during the holiday season, time and budget constraints mean that managers and employees are often left to pick up the work of other colleagues, increasing an already rising workload.
Only 17% of HR directors say that work is put on hold in order to avoid overloading other team members during the holiday season. However, this percentage rises to 24% of medium sized companies, who are less likely to have spare team members on hand to take on extra duties.
Similarly, it is the minority (15%) of HR directors that would engage temporary/contract staff to spread the workload among the team. However, this figure increases to more than one in four (26%) for medium sized businesses and decreases for small (13%) and large (8%) sized businesses.
Phil Booth, director, OfficeTeam said: "With the summer holiday season now well underway, it's likely that employers will find themselves having to cope with multiple staff members being out of the office at the same time. There is an increasing likelihood that managers will be faced with the option of either finding a way to effectively manage a team reduced in number, or to seek coverage for those team members out of the office.
"Managers have to perform a balancing act in which essential work is completed without overtaxing a team that may already be stretched too thin. Holidays can place further pressure on other team members, increasing the chances of stress and anxiety, so it is interesting to see the popularity of different strategies for managing workloads depending on the size of the business."
