Data for the poll, Ramadan in the Middle East and North Africa Workplace, was gathered online between 17 and 29 May 2016 and involved more than 3,660 respondents.
The survey found that 63.5% of observant Muslims believe that Ramadan lifts overall morale at work, while 56.3% noticed an increase in charitable activities in their firms during the month, during which they may not eat or drink between dawn and sunset. Some 53.7% socialised more with their co-workers.
The majority of those who took part in the survey (53.7%) do not take time off during Ramadan, though 56.9% said they do travel during Eid (the religious holiday that marks the end of Ramadan).
Bayat.com's online questionnaire includes responses from workers from the UAE, Bahrain, Algeria, Egypt, Iraq, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Tunisia, Qatar, Saudi Arabia and Yemen.
Ramadan is the favourite time of year for 86.8% of MENA professionals, with more than eight in ten (81.1%) seeing more family and friends during the holy month. Almost 95% of them give more to charity during this period.
"There are substantial changes in the MENA workplace during the month of Ramadan, and it is important for both employers, employees and job seekers to have a clear view of what to expect during this time," said Suhail Masri, vice-president of employer solutions at Bayt.com.
"It is interesting that more than three in every five respondents believe that their morale is lifted during Ramadan, which is something employers can use to build employee loyalty, engagement and retention."
