I hold out, yes, for what every worker is entitled to have (7)
I believe the answer is:
holiday
'what every worker is entitled to have' is the definition.
I can't tell whether this definition defines the answer.
'i hold out yes' is the wordplay.
'out' means one lot of letters goes inside another.
'yes' becomes 'ay'.
'i' placed into 'hold' is 'holid'.
'holid'+'ay'='HOLIDAY'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for holiday that I've seen before include "See 8" , "jazz singer" , "Day of festivity" , "rest" , "given a break" .)
