depends!

some companies operate double shift, various permutations existing, as an example some work 8-12 4-8pm
for 6 days a week. Normal Qatari practice is 48 hour week, with earlier finish on thursday, friday off for most workers. Pure hell!

now a lot of companies are changing but most want their pound of flesh! 45 to 48 hours is common + unpaid overtime for senior staff.

Government timings are better, usually 35 to 37 hours straight shift, This allows Qataris to visit their private businesses in the evening!
