Should employee do the follow-up jobs when he is on long leave on medical ground

Can a Management blame the employee for not doing the follow-up job during his approved leaves which was on an medical grounds for a week.

Dear friend,
What is the exact meaning of follow-up job? Who was expected do follow up and of whom?
Leave is defined as "absence from work or duty". Now in the course of absence, employee is not expected to do any direct or indirect duties. If he/she starts working while on leave then what is difference between while at work and leave?
Above explanation apart, designation of a person also matters. Sometimes, senior managers continue to remain connected with their work while on leave also. Nevertheless, making a person to work even while on leave speaks about poor culture of the company. The real strength of a manager lies ensuring that everything goes smoothly even at his/her absence. These kind of issues arise when there is very less manpower and the work is person-centric and not process-centric.
All said and done, finally it depends on the subordinates how to maintain relationship with his/her boss. If it is required to do follow up so as to keep the boss in good humour then it is better to fall in line and accept the demands of the boss!

Thank you sir, the employee is in executive level. He had applied leave for his surgery, as it was a planned leave he had updated his pending tasks to his backup and also instructed what to be followed.
Doctor had advised him to take 2weeks leave, but he was granted only 1week leave even though he had his SL balance. The day when he resumed to his work he was questioned for not doing follow-up from home.
Due to this the management states that, they need to think over on his promotion.

Threatening an employee for not working during sick leave is poorest of poor practises.
Employee should quietly look for better options and move on from such heartless companies.

From the post it can be considered that , employee was expected to do the regular followup of the clients he was handling. However, expecting this while employee is unfit in performing his duties is just unprofessional and selfish act. I agree with such Nathrao sir , one should not work with company which lacks sense of compassion.
