When financial advisors say put away for 6 monthe emergency, how does

[white brick home]

unemployment pay come in? My boyfriend gets laid off somewhat regularly as a construction worker, and even more so with the economy. We are aiming to put away a 6 month emergency fund, but here is the question:
Say
X is expenses
Y is unemployment pay
Z is emergency savings

is it Y+Z=X
or Z=X?

thanks!
