Overtime work rarely pleases anyone, but it is scary to refuse it because of the risk of ruining relations with management.
After all, working conditions, pay and career largely depend on management.
But I also don’t want to waste my time, energy and effort on extra work for “thanks”.
Many people feel awkward asking this question, but any additional work should be paid. This will immediately show your willingness to take on additional responsibilities, but for material compensation.
If the job offered was unpaid, then in most cases it will be offered to another employee.
You can always refer to the fact that additional responsibilities will become an obstacle to the flawless execution of your tasks.
This is a very worthy argument in your favor.
Yes, this method cannot be called flawless from the point of view of friendship, but it can also be used. You can always point to a more experienced person who will cope with the specified task much better than you.
