Key operation for bosses wanting to keep control? (7)

Ross

I believe the answer is:

lockout

I'm a little stuck... Click here to teach me more about this clue!

'key operation' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see a link between them that I don't see?

'bosses wanting to keep control?' is the wordplay.
I cannot quite understand how this works, but
'control?' could be 'lock' (lock is a kind of control) and 'lock' is found within the answer.
The remaining letters 'out' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

'for' is the link.

Can you help me to learn more?

(Other definitions for lockout that I've seen before include "Labour dispute" , "management action" .)
