Dear Vanitha,
Thanks for the Question and believing in CiteHr site, Members/Seniors/Moderators as a Good Adviser.
There are many good suggestion given my all respected Seniors, Moderators & Members, some has taken sensitively, some has express Professionally and some as Generally.
So by different type of views I hope you can easy got the conclusion and able to implement or Handle this simple issue professionally.
I just want to mention few points as other did.
1, The mention issue is not big, so its not necessary to go with higher management attention, but for your safe side, you can address it.
(But keep in mind as a good person no one should effect by losing Job)
2, Only two Mandatory Prayer come in during office hours, so Afternoon Prayer (Zohar) can be merged along with lunch time and for Evening Pray (Asar) you can give just 15 mins.
3, If in case work getting effected, if four or five person leaving together for prayer, then you can request them to go two person at same time, and once they come back then other can go.
As prayer can also be offered individual or group of two or three person at a time.
4, You can suggest them to bring Prayer Rug/carpet along with them and allocate some small place in any area which should be clean and advice them to pray individual or in group of two person.
Further to avoid more delay going out in mosque and coming back. (This I used to Do at Present).
5, You should be informed to the employee’s who going for the Prayers, that the time allowing for the prayer is just for the prayers, so kindly don’t misuse it.
(The person who ask time for prayer he just mean it, but I knew some of them just misuse as said by many comments, suggestion, just to escape from work, which is really not tolerated)
6, Lastly, in my point of view, if a person offer prayers either Muslim, Hindu, Christian, Sikh, they offered by the bottom of heart and that make Him/Her to avoid think bad or do bad.
In which the productively of the company automatically increased.
So kindly take up this matter easily and implement some simple rules in the benefit of organizer as well as Employee.
Thanks.
