It is permissible to perform Friday Prayer as Zhuhr Prayer at work sites and at the due time of Zhuhr Prayer if you are unable to perform Friday Prayer in congregation.It is impermissible to
delay Maghrib and Fajr prayers or any other obligatory prayers after their due time; rather a Muslim should offer Prayers at their due time even individually if he is unable to perform them in congregation with other work colleagues, because Allah made such prayers prescribed at fixed times. Allah (Exalted be He) says: (Part No. 5; Page No. 132)
Verily, As-Salât (the prayer) is enjoined on the believers at fixed hours.
So keep your duty to Allâh and fear Him as much as you can
If a Muslim is able to offer Prayer with his co-workers in congregation, they should do so; otherwise they can offer it alternatively or even individually due to the general meaning of the above mentioned Ayah (Qur'anic verse).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
