Another line of future research may be considered in investigating the relationship
between profitability of the hospitality operation and the implementation of internal
marketing programs. It may also include other areas or relationships, for instance, cost
reduction, staff turnover and absenteeism reduction. Additionally, investigation of the
selection of the channels of disseminating information between employees and
management and their effectiveness has to be studied. Another area would be assessing
the weights of each of the four dimensions of the internal marketing on the employees’
perceptions and their effectiveness on the implementation process.
