Q n A : She had some problems after telling her boss about a bad woman at work

Praise be to Allah.
Offering sincere advice to the slaves of Allaah is one of
the most important branches of faith and symbols of Islam, to such an
extent that the Prophet (peace and blessings of Allaah be upon him)
described it as being the religion itself, as an indication of its great
importance. The Prophet (peace and blessings of Allaah be upon him)
said: “Religion is sincerity (or sincere advice – naseehah).”
(Narrated by Muslim, 55). And Allaah tells us that whoever does this, that
is true success. Allaah says (interpretation of the meaning): 

“Let there arise out
of you a group of people inviting to all that is good (Islam), enjoining
Al-Ma‘roof (i.e. Islamic Monotheism and all that Islam orders one to do) and
forbidding Al-Munkar (polytheism and disbelief and all that Islam has
forbidden). And it is they who are the successful”

[Aal ‘Imraan 3:104]

So long as you fulfilled your duty of offering sincere
advice, and your intention was good, then do not feel sad about the problems
that have befallen you (which is a test), for Paradise is the reward of
Allaah, and the reward of Allaah is precious and is surrounded with
hardships, and everything has a price. 

Remember that everyone who does this great duty will
inevitably meet with harm from people, or opposition. Hence Luqmaan the Wise
said to his son: 
“O my son! Aqim‑is‑Salaah
(perform As‑Salaah), enjoin (on people) Al‑Ma‘roof  (Islamic Monotheism and
all that is good), and forbid (people) from Al‑Munkar (i.e. disbelief in the
Oneness of Allaah, polytheism of all kinds and all that is evil and bad),
and bear with patience whatever befalls you. Verily, these are some of the
important commandments (ordered by Allaah with no exemption)”

[Luqmaan 31:17]

Remember that the good end is for the pious (those who fear
Allaah), and Allaah will not cause the reward of those who do good to be
lost, and He is with those who are patient. So turn to Him and seek His
protection, and say Allaah (Alone) is Sufficient for me, and He is the Best
Disposer of affairs (for me). Allaah says (interpretation of the meaning): 

“Those (i.e. believers) unto whom the people (hypocrites)
said, ‘Verily, the people (pagans) have gathered against you (a great army),
therefore, fear them.’ But it (only) increased them in Faith, and they said:
‘Allaah (Alone) is Sufficient for us, and He is the Best Disposer of affairs
(for us).’

174. So they returned with grace and bounty from Allaah.
No harm touched them; and they followed the good Pleasure of Allaah. And
Allaah is the Owner of great bounty”

[Aal ‘Imraan 3:174-175]

No matter how much they plot against you, their plot will
backfire on them. 

“But the evil plot encompasses only him who makes it”

[Faatir 35:43]
So receive the glad
tidings of the help and support of Allaah, make a lot of du’aa’ and pray for
forgiveness. Remember that the prayer of the one who has been wronged or
oppressed is not rejected, as the Prophet (peace and blessings of
Allaah be upon him) said: “There are three whose prayers will undoubtedly be
answered: the prayer of a father, the prayer of a traveller, and the prayer
of one who has been wronged.” Narrated by Abu Dawood, 1536; al-Tirmidhi,
1905; Ibn Maajah, 3862; classed as hasan by al-Albaani in Saheeh Abi
Dawood. 
But we advise you to
leave this job and relieve yourself of that in which there is evil and harm,
and to move to another place; may Allaah give you someone better than them
and give you a trustworthy and kind boss. 
If you cannot move from
this place, then try to take a leave of absence for a while until things
calm down; Allaah may cause things to change. 
If you can do without
this job altogether, and save yourself from all this trouble and heartache
and devote your efforts to taking care of your house and children, then this
is best, and Allaah will reward you for that with His blessings and
compensate you with something better.  
We ask Allaah to relieve
your distress and take away your sorrow, and to protect you against the evil
of every evil person. 
And Allaah knows best.
