Thanks for the above advice, catalystik.
If I've worked for two consecutive summers at the same location, doing the same thing, would you suggest I put:
Start date: May 2006
End date: August 2007
Hrs/wk: 40
a) And just add a line in my description making it clear that I
only worked during the two summers encompassed in that time span, or
b) average the total number of hours over the total time period (=~16 hrs/wk)?
I ask because
LizzyM once noted someone doing the above (without clarification I assume), and took issue with the appearance that they worked 40 hrs/wk year-round.
