The BA mainline 336 services ceased in June 1981....started again in November. Ceased again in May 1982....started again in October. Ceased again in May 1983 finally. Services during that period were mostly Africa and the Middle East. Also ad hoc charters here and there plus freight work for people like Pelican. Those of us that were senior enough went on to 747 the rest took up a secondment with Air Mauritius for a couple of years
