From the point of view of an employee, there are several options:
If a specialist knows his own worth, understands the situation, objectively evaluates the market, and accordingly understands his price in the market and the level of demand, he will do:
1.1. He will say, "Chief, I understand everything. I am also very sorry. I make a decision - to leave the company and change employers." This is the answer of a confident person.
1.2. If a hired specialist is confident in himself, and loves and respects the company, and wants to help her, he will say “OK, Chief, I understand everything, times are difficult.
Let's try to pull the company, I'm ready, 3 months to work for 50%. But then we return to 100% and additional motivation, as compensation for my support of the company with my pocket. "This is the answer of a confident person who is related and loves the company.
1.3. If a hired employee is not confident in his abilities, he will most likely say "Chief, ok, I understand, I'm fine, I'll work for 50%". This is the answer of a weak man. Then he will "bite his elbows", get angry at the boss, at the company, look for a job for half a day, go to interviews, ... And nothing good will happen. As the saying goes "The boss will pretend that he pays the salary, the hired employee will pretend that he is working
1.4 Other options are also possible - tantrums “how will I live on 50% of my salary”, “I will complain about you to the tax police”, “if you don’t pay 100%, I will go to competitors and sell all the information” and so on
