Power and responsibility is given or taken by yr boss...
But in general , if u r an executive, u administrate, decision
making, directing...
It just depends what u administrate , what decision u make and what
u direct.
For example, if yr decision making is worth 100 billion,
definitely, yr salary wont below 5k per month...
u can be an executive with executive paid but yr power and
responsiblity may be stripped by yr boss... Then, u tan tio lor if
u r not fired ...
likewise, u can be an executive but more power and responsibility
given to u by yr boss... Then, u have the experience which means
that u will have the chance to get promoted...
