A widely accepted industry benchmark for HR staffing is:
1 full-time HR professional per 100 employees.
This rule of thumb is used across many industries (especially in North America) and is supported by organizations like SHRM (Society for Human Resource Management).
For 160 employees, you would typically expect:
1.5 to 2 HR staff — meaning either:
2 full-time HR representatives, or
1 full-time HR generalist and 1 part-time or specialized HR support (e.g., payroll, benefits coordinator).
