Depend on department and employee
Dependent on your position in the company working hour can vary massively, the communications and interior design teams work in the day time whereas sales have to start early 7/8am and finish late 10:30/11pm (not on the same shift though, of course). Part time co workers have to work 3 out of 4 weekends in a month and full time co workers get every other weekend off.
Hours are really good for part time and full time workers
Some times the hours worked could be unsuitable for some people.
