''Firing'' is a common colloquial term in the English language (particularly used in the U.S.) for termination. The term ''firing'' may have been initiated in the 1910s at the National Cash Register Company. Other terms for dismissal are being ''sacked'', ''canned'', ''let go'', ''ran-off'', ''axed'', ''given walking papers'', ''given the pink slip'' or ''boned''. Other terms, more often used in Commonwealth countries, include ''to get the boot'' and ''to get the sack''.

Can we conclude that is job termination the same as being fired?
yes
