Do you like Sundays (first working day of the week) or Thursdays (last working day of the week)? does your productivity level changes with the week day?

Level of Productivity is actually constant throughout the entire week. The stress level actually declines as the week ends, but who doesn't like Thursday? I'm sure people are somewhat mentally relaxed on Thursdays because of the excitement of planning  what they will do on the night or on their off days.

Yes, with the amount of pressure at the beginning of the week and by end of the week is always different; which changes the level of productivity. Again it depends upon the number of working hours in the office.

Mostly it depends on the type of work and stress level attached to the task however the thursdays are always exciting as you get time for your family at weekends to enjoy with.

Secondly the first working day is rather Challenging also.

work productivity not only depend on the days,its may be a consider a one factor because starting working day is more pressure and load of work,but work productivity also effect on teame management, effects of flexible working and the regulation of working hours and a little bit  attention is paid to temporal variance in productivity.

Sunday, as first working day of the week , productivity in work doest change anyway.

Every work days is a day.

Productivity level depends on teamworks.

yes in these week working day have different and relax

The level of productivity is a different thing which can't be measure by the week's day. This is totally depends on the responsibility and target you set to deliver tasks. Sometime the week's beginning is too important to deliver the tasks instead of week's end and vice versa.
