Musculoskeletal disorders among female and male air traffic controllers performing identical and demanding computer work

Operators with identical, demanding computer work (90 female and 97 male air traffic controllers) were found to have high prevalences of disorders (assessed by questionnaire and physical examination) in neck, shoulders and upper back. In spite of the identical work, the women displayed higher prevalences than the men (e.g. neck diagnoses 21% vs. 4%). Disorders in elbows, wrists and hands were less common, with similar rates in both genders. Generally, the psychosocial work environment (assessed by questionnaire) was found to be good, but with large inter-individual variation. Women experienced lower decision latitude than men, particularly regarding influence and freedom at work, but perceived higher social support. Physically, the work was characterized by relatively low angular velocities of upper arms (measured by inclinometry) and wrists (right: <1°/s during 19% of time, measuring by goniometry), dynamic muscular activities and high time fractions of rest in the trapezius and forearm extensor muscles (measuring by electromyography). There were only minor differences between the genders.

A two-way approach of congruent behavior between leaders and staff in the employeeship concept: Test of model, questionnaires, and influence on climate

Purpose – The authors have developed the Leadership‐Employeeship‐Relationship Model and a questionnaire following their conceptualization of the employeeship concept. It is possible to separately study leadership, peer employee, and interactive leader‐follower behaviors. The purpose of this paper is to examine the relationship between the conceptualization and operationalization, as well as between the model and psychological climate.Design/methodology/approach – In total, four organizations operating at an airport participated. The quantitative approach involved data gathered from expected leadership and employee behaviors and psychological climate attitude questionnaires. The leadership and peer employee variables are separately based on the leadership and employeeship questionnaires, whereas the leader‐follower variable is based on the results of both questionnaires. All analyses were made on the variable level.Findings – The results show that expected leadership, peer employee, and congruent leader‐fo...
