Difference between frictional unemployment and seasonal unemployment Julie spent the entire summer of 2007 working for a tree planting company in Central British Columbia. At the end of July, her contract ended because of weather conditions. She spent the month of August looking for a job but was unsuccessful. In September of 2017 Julie stopped looking for work and instead decided to attend the UBC. As a result, Julie would be considered seasonally unemployed in August but would not be unemployed in September because she is not part of the labour force.  

I cannot figure out if this paragraph is true or false. I think it is frictional unemployment in August as she is actively looking for jobs. But it also fits for the seasonal unemployment since she is dismissed because of weather condition. So I dont know how to define this situation.
What "seasonally unemployed" means? 

First, to be "unemployed", one must actively be seeking for work, as the OP stated. The adjective "seasonally" here would reflect the fact that Julie is looking for a seasonal job, and couldn't find any. But this information is not provided to us. Irrespective of her past employment, Julie may have been looking for a permanent job, in which case she should not be categorized as "seasonally unemployed".
