the C-I-C was known as Senior Chief Steward (SCS). One year later, it was changed to Inflight Supervisor (IFS). Effective 1 April this year, it will be known as Inflight Manager (IFM). I do not know the reason/s why it is retitled to IFM.
As for the first change from SCS to IFS, the reason was because the IFS salary scale was one step higher than the SCS (SCS and CS was in the same salary range).
However, the retitling of IFS to IFM does not involve any change in salary structure nor condition of work. The present basic salary of the IFS/IFM is between $2,650 - $4,260. However, as far as I know all IFS/IFM starts with around or more than $3,675 unless he/she is promoted when he/she was a junior CS or CSS (so called high flyer) whose basic salary is between $2,300 - $3,675.
