How about installing and maintaining broadband phones in telecom companies? Are you tired? What kind of danger is it? I heard there was danger.

This does not belong to China Telecom. You belong to a telecom outsourcing company, which means that you are a contract worker or a temporary worker, not a regular telecom employee. Do not enjoy five insurances and one gold, do not enjoy public holidays, and do not enjoy the salary increase accumulated by working years. There are many such companies, such as China Telecom Service Company, which is a good one and belongs to an industrial company. Then there are other outsourcing companies, depending on which company you have joined. The employees of China Telecom are only the logistics personnel of local companies, and the rest of the business halls and maintenance centers belong to outsourcing companies. The treatment can only be said to be very general, and the danger is far from it, just that it is very hard.
