When someone wants something, anything, even a little bit, they have set their heart upon it. The sin of coveting applies to wanting something that that doesn't belong to them. Wanting money from an employer is coveting, as inconvenient as that may be for some people, that's the reality because words have meanings.
Exodus 20:17 KJV
17Thou shalt not covet thy neighbour's house, thou shalt not covet thy neighbour's wife, nor his manservant, nor his maidservant, nor his ox, nor his ass,
nor any thing that is thy neighbour's.
Romans 13:9 KJV
9For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness,
Thou shalt not covet; and if
there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself
Ephesians 5:3 KJV
3But fornication, and all uncleanness, or
covetousness, let it not be once named among you, as becometh saints;
1 Timothy 6:10 KJV
10For the love of
money is the root of all evil:
which while some coveted after,
they have erred from the faith, and pierced themselves through with many sorrows.
That's nice and all, but the Bible defines coveting as wanting "anything" that belongs to our neighbour. Please see Ex. 20:17 below So while there is some truth in what you're saying, it's wrong. If someone wants anything that belongs to someone else then that's coveting and the Bible says it's a sin. The employer owns the money before giving it to employees. When employees want their employer's money, that's the definition of coveting. Just saying.
Exodus 20:17 KJV
17Thou shalt not covet thy neighbour's house, thou shalt not covet thy neighbour's wife, nor his manservant, nor his maidservant, nor his ox, nor his ass,
nor any thing that is thy neighbour's.
