Evidently unhappy employee, one observing hands on face? (5-7)
I believe the answer is:
clock-watcher
'evidently unhappy employee' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'one observing hands on face?' is the wordplay.
'one observing hands' becomes 'watcher' (I can't explain this - if you can you should believe this answer much more).
'on' means one lot of letters go next to another.
'face?' becomes 'clock' (clock face is a kind of face).
'watcher' put after 'clock' is 'CLOCK-WATCHER'.
Can you help me to learn more?
(Other definitions for clock-watcher that I've seen before include "One impatient to leave work" , "Worker too aware of the time" , "Worker preoccupied with finishing time" , "One who can't wait to stop work" .)
