Ruling on someone who works in Hajj but does not do Hajj because he is unable to do it

Hajj is only obligatory for the one who is able to do it,
because Allah, may He be glorified and exalted, says (interpretation of the
meaning):

“And Hajj (pilgrimage to Makkah)
to the House (Ka‘bah) is a duty that mankind owes to Allah, those who can
afford the expenses (for one’s conveyance, provision and residence)”

[Aal ‘Imraan 3:97].

The definition of ability in this case has been discussed
in fatwa no.
5261.

Whoever meets this definition of being able to do it must
hasten to do Hajj, because doing it immediately is obligatory, according to
the most correct scholarly view. This has been discussed previously in fatwa
no.
155378.

Undoubtedly if a person lives in Makkah and works in Hajj,
then it would be thought most likely that he will be able to perform the
obligatory rituals of Hajj in one way or another, or at least he is more
likely to be able to do it than others, because he does not have to bear the
expenses of travel, obtaining a visa and the like. So he could reach an
agreement with the people he works for so that he may be given permission at
the time when the obligatory rituals are performed, and this is something
easy, in sha Allah. So on the Day of ‘Arafah, either his work will be in
‘Arafah, so he can fulfil the aim of of the muhrim (pilgrim in ihram), which
is to be present in ‘Arafah, and he is not required to make any extra
effort; or if his work is far away from there, then he can go and stay there
to, because there is little need for people outside of ‘Arafah at that time.

Similarly with regard to staying overnight in Muzdalifah
and stoning the Jamaraat; performing the obligatory component of these
actions is also possible, in sha Allah. But if his boss does not agree to
allow him to do Hajj, then in this case it may truthfully be said that he is
not able to do Hajj, as has been explained previously in fatwa no.
155378.
In that case he should organise his affairs so that he can perform Hajj in a
future year, in sha Allah.

What the boss should do is give his worker permission to do
Hajj, especially if it is the obligatory Hajj, because helping a Muslim to
perform this important pillar of Islam brings an immense reward.

And Allah knows best.
