In reality, we play many roles in a day, in our lives. It will be extremely difficult if we mix business with pleasure. A line must be drawn, or else it will effect not only business in dollars and cents, it spells chaos a the office,not to mention an already upside down family life.
Such attitude must not be tolerated at work, and I believe no staff is indispensable too. Extra marital affair is a sin of inadequate self respect, inability in handling personal crisis and an easy way out of facing and confronting personal problems. If, at home, it is already a disaster and one is incapable in controlling wreaks, it will seep at work.
Thus, from a HR practitioner point of view, action as per company's guidelines must be adhered. Absenteeism (mc) out of this can call for verbal/warning letters.Company's decision should be made based from a business point of view,and any transfer for that matter should not be based on an employee's unprofessional attitude.
We are bounded by culture,yes,as a husband/wife,our responsibilities expand to a duty of a son/daughter, a father/mother,uncle/auntie, friends and workers.When we get lost in the many roles we play,we loose our balance.
